[BRCA mutations and decision regret: a comprehensive analysis of existing research through a scoping review and reflections from a nursing perspective.] / Mutazioni BRCA e rimpianto decisionale: un'analisi approfondita della ricerca esistente tramite scoping review e riflessioni da una prospettiva infermieristica.

INTRODUCTION: Given the significance of healthcare decisions in women with BRCA1 and BRCA2 mutations and their impact on patients' lives, this study aims to map the existing literature on decision regret in women with BRCA1 and BRCA2 mutations. METHODS: A scoping review was conducted in the following databases: PubMed, Embase, Scopus, CINAHL, Cochrane, and Google Scholar. Inclusion criteria focused on decision regret in the female population with BRCA1 and/or BRCA2 mutations, with no restrictions on the methodologies of the included studies, but only in the English language. The selection process led to the inclusion of 13 studies. RESULTS: The analysis revealed a significant trend toward decision regret among patients facing complex medical choices. The quality of healthcare communication, decision support, and genetic counselling emerged as key factors influencing patients' perceptions and experiences, with direct implications for their quality of life and psychological well-being. The results suggest that these decisions considerably impact patients, both in terms of clinical outcomes and emotional experiences. DISCUSSION: The investigation highlights the vital importance of a personalized care approach, emphasizing the critical role of managing patients' emotional and psychological complexity. Managing decision regret requires acute attention to individual needs and effective communication to mitigate emotional impact and improve patient outcomes. CONCLUSIONS: Insights from a nursing perspective in the analysis of results indicate the need for informed, empathetic, and integrated care that considers the emotional complexity of women with BRCA1 and/or BRCA2 mutations in their lives and health choices.

TARGET: A Randomized, Noninferiority Trial of a Pretest, Patient-Driven Genetic Education Webtool Versus Genetic Counseling for Prostate Cancer Germline Testing.

PURPOSE: Germline genetic testing (GT) is important for prostate cancer (PCA) management, clinical trial eligibility, and hereditary cancer risk. However, GT is underutilized and there is a shortage of genetic counselors. To address these gaps, a patient-driven, pretest genetic education webtool was designed and studied compared with traditional genetic counseling (GC) to inform strategies for expanding access to genetic services. METHODS: Technology-enhanced acceleration of germline evaluation for therapy (TARGET) was a multicenter, noninferiority, randomized trial (ClinicalTrials.gov identifier: NCT04447703) comparing a nine-module patient-driven genetic education webtool versus pretest GC. Participants completed surveys measuring decisional conflict, satisfaction, and attitudes toward GT at baseline, after pretest education/counseling, and after GT result disclosure. The primary end point was noninferiority in reducing decisional conflict between webtool and GC using the validated Decisional Conflict Scale. Mixed-effects regression modeling was used to compare decisional conflict between groups. Participants opting for GT received a 51-gene panel, with results delivered to participants and their providers. RESULTS: The analytic data set includes primary outcome data from 315 participants (GC [n = 162] and webtool [n = 153]). Mean difference in decisional conflict score changes between groups was -0.04 (one-sided 95% CI, -∞ to 2.54; P = .01), suggesting the patient-driven webtool was noninferior to GC. Overall, 145 (89.5%) GC and 120 (78.4%) in the webtool arm underwent GT, with pathogenic variants in 15.8% (8.7% in PCA genes). Satisfaction did not differ significantly between arms; knowledge of cancer genetics was higher but attitudes toward GT were less favorable in the webtool arm. CONCLUSION: The results of the TARGET study support the use of patient-driven digital webtools for expanding access to pretest genetic education for PCA GT. Further studies to optimize patient experience and evaluate them in diverse patient populations are warranted.

Disease features and management of cardiomyopathies in women.

Over the last years, there has been a growing interest in the clinical manifestations and outcomes of cardiomyopathies in women. Peripartum cardiomyopathy is the only women-specific cardiomyopathy. In cardiomyopathies with X-linked transmission, women are not simply healthy carriers of the disorder, but can show a wide spectrum of clinical manifestations ranging from mild to severe manifestations because of heterogeneous patterns of X-chromosome inactivation. In mitochondrial disorders with a matrilinear transmission, cardiomyopathy is part of a systemic disorder affecting both men and women. Even some inherited cardiomyopathies with autosomal transmission display phenotypic and prognostic differences between men and women. Notably, female hormones seem to exert a protective role in hypertrophic cardiomyopathy (HCM) and variant transthyretin amyloidosis until the menopausal period. Women with cardiomyopathies holding high-risk features should be referred to a third-level center and evaluated on an individual basis. Cardiomyopathies can have a detrimental impact on pregnancy and childbirth because of the associated hemodynamic derangements. Genetic counselling and a tailored cardiological evaluation are essential to evaluate the likelihood of transmitting the disease to the children and the possibility of a prenatal or early post-natal diagnosis, as well as to estimate the risk associated with pregnancy and delivery, and the optimal management strategies.

Development of an Electronic Decision Aid Tool to Facilitate Mainstream Genetic Testing in Ovarian Cancer Patients.

BACKGROUND: Multigene panel testing is an important component of cancer treatment plans and risk assessment, but there are many different panel options and choosing the most appropriate panel can be challenging for health care providers and patients. Electronic tools have been proposed to help patients make informed decisions about which gene panel to choose by considering their preferences and priorities. MATERIALS AND METHODS: An electronic decision aid (DA) tool was developed in line with the International Patient Decision Aids Standards collaboration. The multidisciplinary project team collaborated with an external health care communications agency and the MGH Cancer Center Patient and Family Advisory Council (PFAC) to develop the DA. Surveys of genetic counselors and patients were used to scope the content, and alpha testing was used to refine the design and content. RESULTS: Surveys of genetic counselors (n = 12) and patients (n = 228) identified common themes in discussing panel size and strategies for helping patients decide between panels and in identifying confusing terms for patients and distribution of patients' choices. The DA, organized into 2 major sections, provides educational text, graphics, and videos to guide patients through the decision-making process. Alpha testing feedback from the PFAC (n = 4), genetic counselors (n = 3) and a group of lay people (n = 8) identified areas to improve navigation, simplify wording, and improve layout. CONCLUSION: The DA developed in this study has the potential to facilitate informed decision-making by patients regarding cancer genetic testing. The distinctive feature of this DA is that it addresses the specific question of which multigene panel may be most suitable for the patient. Its acceptability and effectiveness will be evaluated in future studies.

Improving counseling effectiveness with virtual counselors through nonverbal compassion involving eye contact, facial mimicry, and head-nodding.

An effective way to reduce emotional distress is by sharing negative emotions with others. This is why counseling with a virtual counselor is an emerging methodology, where the sharer can consult freely anytime and anywhere without having to fear being judged. To improve counseling effectiveness, most studies so far have focused on designing verbal compassion for virtual counselors. However, recent studies showed that virtual counselors' nonverbal compassion through eye contact, facial mimicry, and head-nodding also have significant impact on the overall counseling experience. To verify this, we designed the virtual counselor's nonverbal compassion and examined its effects on counseling effectiveness (i.e., reduce the intensity of anger and improve general affect). A total of 40 participants were recruited from the university community. Participants were then randomly assigned to one of two virtual counselor conditions: a neutral virtual counselor condition without nonverbal compassion and a compassionate virtual counselor condition with nonverbal compassion (i.e., eye contact, facial mimicry, and head-nodding). Participants shared their anger-inducing episodes with the virtual counselor for an average of 16.30 min. Note that the virtual counselor was operated by the Wizard-of-Oz method without actually being technically implemented. Results showed that counseling with a compassionate virtual counselor reduced the intensity of anger significantly more than counseling with a neutral virtual counselor (F(1, 37) = 30.822, p < 0.001, ηp2 = 0.454). In addition, participants who counseled with a compassionate virtual counselor responded that they experienced higher empathy than those who counseled with a neutral virtual counselor (p < 0.001). These findings suggest that nonverbal compassion through eye contact, facial mimicry, and head-nodding of the virtual counselor makes the participants feel more empathy, which contributes to improving the counseling effectiveness by reducing the intensity of anger.

Survey of genetic counselors identifies a knowledge gap discerning properly regulated cell and gene therapy trials.

BACKGROUND AND AIMS: As cell and gene therapy (CGT) has grown in availability and scope, more unapproved regenerative medicine is being marketed to the public. It is essential that health care providers have sufficient knowledge and comfort to determine whether treatments are properly regulated and address these topics with patients. Due to the applicability of CGT to genetic disease, genetic counselors could be key in providing education and answering patients' questions about these topics. However, previous studies have focused only on physicians' knowledge and comfort with CGT and unapproved regenerative medicine. The purpose of this study was to assess genetic counselors' self-reported knowledge and comfort discussing these topics with patients and to explore what factors predict increased knowledge and comfort. METHODS: The authors designed an online survey distributed to genetic counselors who were part of the National Society of Genetic Counselors Student Research Program e-mail list. The survey addressed genetic counselors' demographics, practice experience with CGT, education about CGT, knowledge and comfort. RESULTS: The survey was completed by 144 genetic counselors. The best predictor of increased knowledge and comfort was experience discussing CGT in practice. In addition, those who worked at an institution at which CGT trials were offered had greater knowledge and comfort. However, most genetic counselors reported their knowledge was not sufficient to address questions from patients, and most had little-to-no knowledge or comfort determining whether a trial was properly regulated. There was no correlation between education and either knowledge or comfort; however, most participants desired more education about these topics. CONCLUSIONS: This study suggests that genetic counselors who (i) have experience with CGT in practice or (ii) work at institutions at which CGT trials are offered may have better knowledge regarding CGT. These results may help identify individuals and/or institutions in whom increasing knowledge regarding CGT could be beneficial. This is crucial as CGT becomes mainstream, leading to more widely marketed unapproved regenerative medicine. Several gaps in knowledge and comfort were identified, including participants' ability to determine whether a treatment is properly regulated. Further research is needed to better characterize the educational needs of genetic counselors surrounding these topics to address these gaps.

[Genetic counselling and testing in pulmonary arterial hypertension - A consensus statement on behalf of the International Consortium for Genetic Studies in PAH - French version]. / Conseil génétique et dépistage de l'hypertension artérielle pulmonaire ­ consensus du Consortium international pour les études génétiques dans l'HTAP ­ version française.

Pulmonary arterial hypertension (PAH) is a rare disease that can be caused by (likely) pathogenic germline genomic variants. In addition to the most prevalent disease gene, BMPR2 (bone morphogenetic protein receptor 2), several genes, some belonging to distinct functional classes, are also now known to predispose to the development of PAH. As a consequence, specialist and non-specialist clinicians and healthcare professionals are increasingly faced with a range of questions regarding the need for, approaches to and benefits/risks of genetic testing for PAH patients and/or related family members. We provide a consensus-based approach to recommendations for genetic counselling and assessment of current best practice for disease gene testing. We provide a framework and the type of information to be provided to patients and relatives through the process of genetic counselling, and describe the presently known disease causal genes to be analysed. Benefits of including molecular genetic testing within the management protocol of patients with PAH include the identification of individuals misclassified by other diagnostic approaches, the optimisation of phenotypic characterisation for aggregation of outcome data, including in clinical trials, and importantly through cascade screening, the detection of healthy causal variant carriers, to whom regular assessment should be offered.

Disability education and implications for genetic counselor training.

The genetic counseling (GC) community has faced criticism about the duality of promoting patient autonomy while also advocating for individuals with disabilities. This study assessed the attitudes of the disability community and GCs to identify content that should be included in GC disability education and evaluate the landscape of GC disability education. Members of the disability community and GCs completed an electronic survey distributed through electronic listservs and partnering organizations. A total of 672 responses were analyzed from both the disability community (n = 596) and the GC community (n = 76). Members of the disability community noted differences in GC comfort level discussing different aspects of disability with GCs being perceived as being very knowledgeable about medical aspects 71% of the time versus 49% of the time when discussing social/lifestyle aspects of disability. This discordance was reflected in GCs reported comfort level in discussing medical aspects (89%) and social aspects of disability (65%) during a session. Most GC respondents (71%) felt they received adequate knowledge during their disability education and variation was reported in the execution of disability education by training programs. Disability education content recommendations from the disability community and GCs included emphasizing four key aspects of disability: medical, social/lifestyle, lived experience, and the disability rights movement. Respondents of both cohorts stressed the inclusion of and exposure to persons with disabilities in disability education to understand the lived experience of persons with disabilities. The disability community identified additional disability education content to be included such as empathy training, family hardships, and mental health. The results of this study have practice implications and provide a foundation for training expectations to ensure future GCs possess the necessary skills to improve the quality of services provided to families and persons with disabilities.

Pretest Video Education Versus Genetic Counseling for Patients With Prostate Cancer: ProGen, A Multisite Randomized Controlled Trial.

PURPOSE: Germline genetic testing (GT) is recommended for men with prostate cancer (PC), but testing through traditional models is limited. The ProGen study examined a novel model aimed at providing access to GT while promoting education and informed consent. METHODS: Men with potentially lethal PC (metastatic, localized with a Gleason score of ≥8, persistent prostate-specific antigen after local therapy), diagnosis age ≤55 years, previous malignancy, and family history suggestive of a pathogenic variant (PV) and/or at oncologist's discretion were randomly assigned 3:1 to video education (VE) or in-person genetic counseling (GC). Participants had 67 genes analyzed (Ambry), with results disclosed via telephone by a genetic counselor. Outcomes included GT consent, GT completion, PV prevalence, and survey measures of satisfaction, psychological impact, genetics knowledge, and family communication. Two-sided Fisher's exact tests were used for between-arm comparisons. RESULTS: Over a 2-year period, 662 participants at three sites were randomly assigned and pretest VE (n = 498) or GC (n = 164) was completed by 604 participants (VE, 93.1%; GC, 88.8%), of whom 596 participants (VE, 98.9%; GC, 97.9%) consented to GT and 591 participants completed GT (VE, 99.3%; GC, 98.6%). These differences were not statistically significant although subtle differences in satisfaction and psychological impact were. Notably, 84 PVs were identified in 78 participants (13.2%), with BRCA1/2 PV comprising 32% of participants with a positive result (BRCA2 n = 21, BRCA1 n = 4). CONCLUSION: Both VE and traditional GC yielded high GT uptake without significant differences in outcome measures of completion, GT uptake, genetics knowledge, and family communication. The increased demand for GT with limited genetics resources supports consideration of pretest VE for patients with PC.

Improvement in cystic fibrosis newborn screening program outcomes with genetic counseling via telemedicine.

INTRODUCTION: The Cystic Fibrosis Foundation (CF Foundation) recommends the provision of genetic counseling (GC) to help educate families and decrease anxiety around the cystic fibrosis (CF) newborn screening process. Unfortunately, access to genetic counselors is limited, especially for CF trained genetic counselors. We hypothesized that the GC process for families could be improved by utilizing telemedicine to leverage the availability of two dedicated, CF trained genetic counselors to provide access to GC for several CF centers. In addition, we hoped to demonstrate that use of trained CF genetic counselors, delivering GC via telemedicine at the time of sweat testing, would provide families with understanding of CF genetics as well as result in high satisfaction with the newborn screening process. METHODS: GC was provided by CF trained genetic counselors via telemedicine at the time of sweat testing. Following the counseling session, families were administered an anonymous written survey to evaluate their impression of the services provided. A subset of 50 families was recruited for an assessment of gained knowledge regarding CF genetics using the Ciske knowledge inventory. Using χ2  analysis, Ciske knowledge inventory data from our telemedicine GC families was compared to counseled and uncounseled Ciske historical controls. Lastly, in-depth interviews about the newborn screening process for CF were performed with 10 families and interviews were coded for emerging themes. RESULTS: During the 4 years of the study, 250 patients received GC. Overall comfort with the counseling rated 4.77 out of 5 using a Likert scale. After counseling by telemedicine, parents demonstrated improved understanding of the genetic implications of an abnormal CF newborn screen for their family, with 100% of families understanding that their child was a carrier for CF as compared to 97.2% of counseled (p = .023) and 78.5% of uncounseled (p = .0007) from Ciske historical controls. The study group also showed improvement in understanding of both parents possibly being carriers, with an 87.7% correct response rate compared to a 37.0% correct response rate in the counseled group (p < .0001) and a 35.4% correct response rate in the non-counseled group (p < .0001) from Ciske historical controls. Subgroup analysis at one site showed a significant increase in the number of infants with completed sweat tests from previous years (49% in 2013 vs. 80% in 2017 during the study, p < .0001). CONCLUSIONS: GC by telemedicine was well received by families and demonstrated improved family knowledge acquisition and understanding of CF as it related to risks for their child as well as identification of risks for other family members. Furthermore, in addition to an increase is those receiving GC, a subgroup analysis demonstrated a significant increase in the number of infants receiving sweat tests. This study demonstrates that GC via telemedicine for CF is feasible and demonstrates improvement in parent understanding of CF genetics. Furthermore, this method can be implemented effectively across a wide geographical area with a limited number of CF trained genetic counselors to improve access to care for patients and families.

Genetic counseling and testing for females at elevated risk for breast cancer: Protocol for the randomized controlled trial of the Know Your Risk intervention.

BACKGROUND: Genetic counseling and testing have an important role in the care of patients at elevated risk for breast cancer. However, conventional pre- and post-test genetic counseling is labor and time intensive, less accessible for patients living outside major urban centers, and impractical on a large scale. A patient-driven approach to genetic counseling and testing may increase access, improve patients' experiences, affect efficiency of clinical practice, and help meet workforce demand. The objective of this 2-arm randomized controlled trial is to determine the efficacy of Know Your Risk (KYR), a genetic counseling patient preference intervention. METHODS: Females (n = 1000) at elevated risk (>20% lifetime) for breast cancer will be randomized to the KYR intervention or conventional genetic counseling. The study will provide comprehensive assessment of breast cancer risk by multigene panel testing and validated polygenic risk score. Primary outcome is adherence to National Comprehensive Cancer Network guidelines for a clinical encounter every 6-12 months and an annual mammogram (breast MRI if recommended) determined by medical record review. Secondary outcomes include adherence to other recommended cancer screening tests determined by medical record review and changes in breast cancer knowledge, perception of risk, post-test/counseling distress, and satisfaction with counseling by completion of three surveys during the study. Study aims will be evaluated for non-inferiority of the KYR intervention compared to conventional genetic counseling. CONCLUSION: If efficacious, the KYR intervention has the potential to improve patients' experience and may change how genetic counseling is delivered, inform best practices, and reduce workforce burden. TRIAL REGISTRATION: ClinicalTrials.govNCT05325151.

Remotely Delivered Cancer Genetic Testing in the Making Genetic Testing Accessible (MAGENTA) Trial: A Randomized Clinical Trial.

Importance: Requiring personalized genetic counseling may introduce barriers to cancer risk assessment, but it is unknown whether omitting counseling could increase distress. Objective: To assess whether omitting pretest and/or posttest genetic counseling would increase distress during remote testing. Design, Setting, and Participants: Making Genetic Testing Accessible (MAGENTA) was a 4-arm, randomized noninferiority trial testing the effects of individualized pretest and/or posttest genetic counseling on participant distress 3 and 12 months posttest. Participants were recruited via social and traditional media, and enrollment occurred between April 27, 2017, and September 29, 2020. Participants were women aged 30 years or older, English-speaking, US residents, and had access to the internet and a health care professional. Previous cancer genetic testing or counseling was exclusionary. In the family history cohort, participants had a personal or family history of breast or ovarian cancer. In the familial pathogenic variant (PV) cohort, participants reported 1 biological relative with a PV in an actionable cancer susceptibility gene. Data analysis was performed between December 13, 2020, and May 31, 2023. Intervention: Participants completed baseline questionnaires, watched an educational video, and were randomized to 1 of 4 arms: the control arm with pretest and/or posttest genetic counseling, or 1 of 3 study arms without pretest and posttest counseling. Genetic counseling was provided by phone appointments and testing was done using home-delivered saliva kits. Main Outcomes and Measures: The primary outcome was participant distress measured by the Impact of Event Scale 3 months after receiving the results. Secondary outcomes included completion of testing, anxiety, depression, and decisional regret. Results: A total of 3839 women (median age, 44 years [range 22-91 years]), most of whom were non-Hispanic White and college educated, were randomized, 3125 in the family history and 714 in the familial PV cohorts. In the primary analysis in the family history cohort, all experimental arms were noninferior for distress at 3 months. There were no statistically significant differences in anxiety, depression, or decisional regret at 3 months. The highest completion rates were seen in the 2 arms without pretest counseling. Conclusions and Relevance: In the MAGENTA clinical trial, omitting individualized pretest counseling for all participants and posttest counseling for those without PV during remote genetic testing was not inferior with regard to posttest distress, providing an alternative care model for genetic risk assessment. Trial Registration: ClinicalTrials.gov Identifier: NCT02993068.

Principles of Genetic Counseling in Inherited Heart Conditions.

Cardiac genetic counseling is the process of helping individuals adapt to a personal diagnosis or family history of an inherited heart condition. The process is shown to benefit patients and includes specialized skills, such as counseling children and interpreting complex genetic results. Emerging areas include: evolving service delivery models for caring for patients and communicating risk to relatives, new areas of need including postmortem molecular autopsy, and new populations of individuals found to carry a likely pathogenic/pathogenic cardiac variant identified through genomic screening. This article provides an overview of the cardiac genetic counseling process and evolving areas in the field.

Lack of guidelines and translational knowledge is hindering the implementation of psychiatric genetic counseling and testing within Europe - A multi-professional survey study.

Genetic research has identified a large number of genetic variants, both rare and common, underlying neurodevelopmental disorders (NDD) and major psychiatric disorders. Currently, these findings are being translated into clinical practice. However, there is a lack of knowledge and guidelines for psychiatric genetic testing (PsychGT) and genetic counseling (PsychGC). The European Union-funded COST action EnGagE (CA17130) network was started to investigate the current implementation status of PsychGT and PsychGC across 35 participating European countries. Here, we present the results of a pan-European online survey in which we gathered the opinions, knowledge, and practices of a self-selected sample of professionals involved/interested in the field. We received answers from 181 respondents. The three main occupational categories were genetic counselor (21.0%), clinical geneticist (24.9%), and researcher (25.4%). Of all 181 respondents, 106 provide GC for any psychiatric disorder or NDD, corresponding to 58.6% of the whole group ranging from 43.2% in Central Eastern Europe to 66.1% in Western Europe. Overall, 65.2% of the respondents reported that genetic testing is offered to individuals with NDD, and 26.5% indicated the same for individuals with major psychiatric disorders. Only 22.1% of the respondents indicated that they have guidelines for PsychGT. Pharmacogenetic testing actionable for psychiatric disorders was offered by 15%. Interestingly, when genetic tests are fully covered by national health insurance, more genetic testing is provided for individuals with NDD but not those with major psychiatric disorders. Our qualitative analyses of responses highlight the lack of guidelines and knowledge on utilizing and using genetic tests and education and training as the major obstacles to implementation. Indeed, the existence of psychiatric genetic training courses was confirmed by only 11.6% of respondents. The question on the relevance of up-to-date education and training in psychiatric genetics on everyday related practice was highly relevant. We provide evidence that PsychGC and PsychGT are already in use across European countries, but there is a lack of guidelines and education. Harmonization of practice and development of guidelines for genetic counseling, testing, and training professionals would improve equality and access to quality care for individuals with psychiatric disorders within Europe.

Need for additional training to be a laboratory genetic counselor-A qualitative exploration.

Opportunities for genetic counselors to work in the laboratory have grown exponentially, yet the professional development needed to serve in these roles had not been previously explored. This study aimed to identify competencies required for entry-level genetic counselors working in the laboratory, explore the perceived level of preparation of these competencies as noted by experts in the laboratories, and assess the perceived value of additional credentialing for genetic counselors practicing in these settings. Twenty genetic counselors working in the laboratory setting and five MD or PhD laboratory managers, identified through purposeful and snowball sampling and with at least 5 years of experience working in a laboratory, were interviewed using a semi-structured protocol. Transcripts were analyzed thematically using deductive and inductive coding. Key findings included the distinction of laboratory and industry roles as involving nondirect patient care and differing from genetic counseling roles in the clinical setting. Genetic counselors working in the laboratory feel well prepared to transition into this setting and provide a unique patient-focused perspective to laboratory roles, including variant interpretation, marketing, and product development. Practice-based competencies (PBCs) were translatable to those used in the laboratory, yet variant interpretation, limitations of genomics-based tests, and the business of health care were noted as important to these roles but not fully addressed in the PBCs. Additional skills were often developed through on-the-job training and interdisciplinary collaboration, but more exposure to diverse roles in genetic counseling programs' didactic and field training was recommended. The majority felt that requiring an additional post-master's credential to work in the laboratory setting may restrict movement into these roles. Several questioned their identity as genetic counselors as they were no longer providing direct patient care and/or had been dissuaded by others from pursuing a laboratory position. Research focused on professional identity among genetic counselors working in nondirect patient care roles is warranted.

Providing genetic testing and genetic counseling for Parkinson's disease to the community.

PURPOSE: To evaluate the feasibility and impact of offering genetic testing and counseling to patients with Parkinson's disease (PD), with the potential to enroll in gene-targeted clinical trials and improve clinical care. METHODS: A multicenter, exploratory pilot study at 7 academic hospital sites in the United States tracked enrollment and randomized participants to receive results and genetic counseling at local sites or by genetic counselors, remotely. Follow-up surveys measured participant/provider satisfaction, knowledge, and psychological impact. RESULTS: From September 5, 2019 to January 4, 2021, 620 participants were enrolled and 387 completed outcome surveys. There were no significant differences in outcomes between local and remote sites, with both arms reporting high knowledge and satisfaction scores (>80%). Notably, 16% of those tested had reportable PD gene variants (pathogenic/likely pathogenic/risk allele). CONCLUSION: Local clinicians, as well as genetic counselors, with educational support as needed, can effectively return genetic results for PD as we observed favorable outcome measures in both groups. Increasing access to PD genetic testing and counseling is urgent; this can inform future efforts to integrate genetic testing and counseling into clinical care for all those with PD.

Current State of Dor Yeshorim, Expanded Carrier, and Newborn Screening: Benefits and Limitations.

ABSTRACT: Availability and accessibility of preconception and prenatal genetic carrier and newborn biochemical and genetic screening have grown exponentially over the past 2 decades and as such, it is challenging for clinicians to keep pace. Although genetic counseling or genetic consultation should be offered to all expectant and new parents for prenatal screening decisions and positive results, benefits and limitations of these tests and results must be known and familiar to perinatal and pediatric clinicians. A brief historical overview of Dor Yeshorim, preconception and prenatal expanded carrier, and newborn screening is presented, followed by discussion about the conditions screened and considerations surrounding the benefits and limitations of these tests in the practice setting.

Germline Predisposition to Myelodysplastic Syndromes.

ABSTRACT: While germline predisposition to myelodysplastic syndromes is well-established, knowledge has advanced rapidly resulting in more cases of inherited hematologic malignancies being identified. Understanding the biological features and main clinical manifestations of hereditary hematologic malignancies is essential to recognizing and referring patients with myelodysplastic syndrome, who may underlie inherited predisposition, for appropriate genetic evaluation. Importance lies in individualized genetic counseling along with informed treatment decisions, especially with regard to hematopoietic stem cell transplant-related donor selection. Future studies will improve comprehension of these disorders, enabling better management of affected patients and their families.

Outcome of premarital genetic counseling for couples at risk of hemoglobinopathies in Kingdom of Bahrain.

OBJECTIVES: Hemoglobinopathies are the commonest inherited blood disorders and form a serious burden worldwide, affecting communities, patient quality of life and healthcare resources. The Kingdom of Bahrain has issued a law obligating couples to undergo premarital screening to detect those at risk of having children affected with these disorders. The aim of this study was to analyze the marital decisions of couples at risk for hemoglobinopathies and follow up the outcomes. METHODS: A retrospective study was conducted on couples at risk for hemoglobinopathies identified during the premarital screening program at local health centers in the Kingdom of Bahrain and referred to the genetics department in the Salmaniya Medical Complex for genetic counselling in 2018-2020. RESULTS: A total of 189 couples were found to be at risk for hemoglobinopathies, of whom 159 completed the survey. Of these, 107 (67%) decided to proceed with their marriage and 26 couples achieved pregnancy. Out of 24 at-risk pregnancies with known outcome, 83.3% were spontaneous whereas only 16.7% underwent in-vitro fertilization (IVF) with preimplantation genetic diagnosis (PGD). Eight out of 20 infants born to couples after spontaneous conception were affected. A positive attitude toward IVF with PGD was held by 60% of at-risk couples. CONCLUSIONS: Despite undergoing premarital screening and genetic counselling, a large percentage of at-risk couples proceeded with their marriage. Most of them justified their decision due to the availability of advanced methods that aid in the prevention of having an affected child. However, the cost of such intervention was a major barrier for the majority of couples.
