Clinical Bootcamp: Moving toward competency outside of the clinic.

The COVID-19 Pandemic placed many challenges on the healthcare system. As healthcare providers were stretched thin and clinics were closed to any non-essential personnel, including learners, educational programs across the country scrambled to meet the needs of their students. In response to restrictions placed on traditional in-person clinical training, the University of Michigan Genetic Counseling Program (UMGCP) designed a Clinical Bootcamp (Bootcamp); a two-weeklong, blended educational activity using a framework of case-based learning (CBL) (McLean, 2016). Journal of Medical Education and Curricular Development, 3, JMECD.S20377). Herein is a description of the theory behind the design as well as specific details of the activities and evaluations to aid implementation and ideas for future applications. Activities developed for the Clinical Bootcamp retain relevance when clinical sites and experienced clinical supervisors are limited resources. We believe the Bootcamp can serve as a tool to expedite the transition of clinical skills to a new setting, allowing students to engage more fully upon entering a new clinical space, leading to optimal use of supervisors' time and experience, and allowing students to maximize the benefit of their time in clinic.

Entrustment decision-making in genetic counseling supervision: Exploring supervisor and student perspectives to enhance training practices.

Entrustment decisions are an essential part of genetic counseling supervision and have the potential to influence a student's progression toward autonomy. However, there is often uncertainty among supervisors regarding how and when to make these decisions and very few studies have examined the impact of these decisions on students. This study utilized a mixed methods approach including surveys of genetic counseling supervisors (n = 76) and students (n = 86) as well as qualitative interviews with genetic counseling supervisors (n = 20) and students (n = 20) that explored factors that influence the entrustment decisions of genetic counseling supervisors and their effect on genetic counseling students. Genetic counseling supervisors and students were recruited from various organizations across the United States and Canada and represented a range of geographic regions, hospital systems, and genetic counseling programs. A hybrid process of deductive and inductive coding and thematic analysis was used to evaluate and interpret transcripts from the supervisor and student interviews. All participants identified advantages of increased autonomy during training. However, many supervisors reported low entrustment, seldom allowing students to complete unsupervised sessions or supervised cases without interruption. Entrustment decisions were heavily influenced by student ability and confidence, as well as patient feedback. Students emphasized the negative impact of decreased entrustment on their confidence and described clear benefits to increased autonomy before, during, and after the genetic counseling appointment. Supervisors identified various barriers to entrustment pertaining to the student, clinical setting, and the patient, whereas students more often emphasized barriers pertaining to themselves. Our results highlight a tension between the clear advantages of increased entrustment and autonomy and various barriers to the provision of these opportunities. Additionally, our data suggest several ways to enhance the supervisor-student relationship and promote additional learning opportunities to support student-centered supervision.

Disclosure of genetic risk to dating partners among young adults with von Hippel-Lindau disease.

Individuals with genetic disease face unique challenges related to navigating dating relationships. While previous studies have explored the impact of hereditary breast and ovarian cancer syndrome on dating, research investigating psychosocial implications for young adults with early-onset multi-organ tumor predisposition syndromes such as von Hippel-Lindau disease (VHL) is scarce. This study assessed young adults' attitudes towards dating and decisions related to disclosing a diagnosis of VHL to a dating partner. Twenty-six young adults with VHL participated in semi-structured interviews exploring this issue, using a guide informed by the literature in consultation with providers and an individual with VHL. Interviews were coded with a primarily deductive approach using codes derived from the literature, with inductive coding employed for perspectives unique to VHL. Our results support previous findings that genetic disease contributes to fear of rejection due to decreased desirability. However, participants report that partners' reactions to VHL uniquely exacerbate this concern due to unfamiliarity with VHL and a perception that it is exceptionally serious, leading to different strategies in disclosure. While many cited negative reactions from partners, participants also described how disclosure can strengthen relationships by deepening trust. Participants discussed a desire for healthcare providers to offer support in this context and described the benefit of speaking with peers about their dating experiences and approaches to disclosure. Our findings provide insight into the diverse needs of young adults with VHL as they approach romantic relationships and decision-making regarding disclosure and highlight the importance of patient-centered support from providers and patient organizations.

Motivational interviewing for genetic counseling: A unified framework for persuasive and equipoise conversations.

Genetic counselors (GCs) have traditionally been trained to adopt a position of equipoise or clinical neutrality. They provide information, answer questions, address barriers, and engage in shared decision-making, but generally, they do not prescribe a genetic test. Historically, GCs have generally been trained not to persuade the ambivalent or resistant patient. More recently, however, there has been discussion regarding when a greater degree of persuasion or directionality may be appropriate within genetic counseling (GC) and what role MI may play in this process. The role for "persuasive GC" is based on the premise that some genetic tests provide actionable information that would clearly benefit patients and families by impacting treatment or surveillance. For other tests, the benefits are less clear as they do not directly impact patient care or the benefits may be more subjective in nature, driven by patient values or psychological needs. For the former, we propose that GCs may adopt a more persuasive clinical approach while for the latter, a more traditional equipoise stance may be more appropriate. We suggest that motivational interviewing (MI) could serve as a unifying counseling model that allows GCs to handle both persuasive and equipoise encounters. For clearly beneficial tests, while directional, the MI encounter can still be non-directive, autonomy-supportive, and patient-centered. MI can also be adapted for equipoise situations, for example, placing less emphasis on eliciting and strengthening change talk as that is more a behavior change strategy than a shared decision-making strategy. The core principles and strategies of MI, such as autonomy support, evocation, open questions, reflective listening, and affirmation would apply to both persuasive and equipoise encounters. Key issues that merit discussion include how best to train GCs both during their initial and post-graduate education.

Improving access to cancer genetic services: perspectives of high-risk clients in a community-based setting.

Cancer genetic services are underutilized by high-risk clients in community-based health settings. To understand this disparity, 108 Planned Parenthood high-risk clients completed a utilization-focused survey. Clients expressed interest (78.8%) and intention (75.0%) in seeking genetic services. Personal/familial implications for cancer risk were the strongest motivators for seeking services (63.0-79.6%). Finances (39.6%) and worry (37.0%) were the biggest barriers. To reduce disparities in access to cancer genetics services, clinicians must understand clients' concerns and tailor their recommendations.

Optimizing efficiency and skill utilization: Analysis of genetic counselors' attitudes regarding delegation in a clinical setting.

This study assessed genetic counselors' (GCs) perceptions of delegation as a tool to increase workforce efficiency and help meet the current gap between the number of genetic service providers and the number of patients. GCs were recruited to participate via an online survey that assessed activities (categorized as typical genetic counseling, administrative, or professional development) performed by a clinical genetic counselor. Respondents indicated which activities represent their largest time consumers, their willingness to delegate these activities, and barriers to and perceived outcomes of delegation. Overall, respondents indicated that they spend 25% of their time performing administrative activities that they would largely be willing to delegate; however, respondents were generally unwilling to delegate many typical genetic counseling and professional development activities, citing concerns regarding accuracy and liability, and highlighting the belief that these activities constitute the core role of a genetic counselor. Respondents indicated that delegation of time-consuming administrative activities would increase access to genetic services and improve job satisfaction. Additionally, differences were identified among clinical specialties regarding which activities were selected as top time consumers, indicating that potential targets of re-allocation of time or delegation may be variable. This research indicates a need to reduce the number of administrative tasks in which GCs are directly involved to re-allocate time toward core responsibilities, direct patient care, and professional development, the result of which is more efficient use of the GC skill-set.

Evaluating and improving the implementation of a community-based hereditary cancer screening program.

Healthcare disparities exist in the provision of cancer genetic services including genetic counseling and testing related to BRCA1/2 mutations. To address this in a community health setting a screening tool was created to identify high-risk women. This study evaluates the implementation of the tool and identifies opportunities for improved cancer genetic screening, including regular clinician education. A mixed-method approach was used to evaluate clinician utilization of the screening tool at Planned Parenthood affiliates. Novel surveys that evaluated acceptance and implementation were administered to clinicians (n = 14) and semi-structured interviews (n = 6) were used to explore clinicians' perspectives and identify gaps in its utilization. Educational modules that addressed gaps were developed, implemented, and evaluated using a post-education survey (n = 8). Clinicians reported confidence in administering and interpreting the screening tool, but reported less confidence in their knowledge of cancer genetics and ability to connect clients with genetic counseling and testing (p = .003). Educational modules resulted in significant gains in clinician knowledge on genetic topics (p < .05) and increased self-reported confidence in connecting clients with genetic services. The modules reinforced the belief that genetic testing is beneficial for patients at increased risk (p = .001) and is important to inform subsequent medical management (p = .027). While building community clinicians' capacity to connect clients with genetic services is crucial, it is challenged by knowledge and confidence gaps in discussions of genetic services with clients. Consistent genetic-focused education with non-genetic clinicians can improve confidence and knowledge, enabling a more effective screening program in community health settings.

A human MUTYH variant linking colonic polyposis to redox degradation of the [4Fe4S]2+ cluster.

The human DNA repair enzyme MUTYH excises mispaired adenine residues in oxidized DNA. Homozygous MUTYH mutations underlie the autosomal, recessive cancer syndrome MUTYH-associated polyposis. We report a MUTYH variant, p.C306W (c.918C>G), with a tryptophan residue in place of native cysteine, that ligates the [4Fe4S] cluster in a patient with colonic polyposis and family history of early age colon cancer. In bacterial MutY, the [4Fe4S] cluster is redox active, allowing rapid localization to target lesions by long-range, DNA-mediated signalling. In the current study, using DNA electrochemistry, we determine that wild-type MUTYH is similarly redox-active, but MUTYH C306W undergoes rapid oxidative degradation of its cluster to [3Fe4S]+, with loss of redox signalling. In MUTYH C306W, oxidative cluster degradation leads to decreased DNA binding and enzyme function. This study confirms redox activity in eukaryotic DNA repair proteins and establishes MUTYH C306W as a pathogenic variant, highlighting the essential role of redox signalling by the [4Fe4S] cluster.

A Case for Inclusion of Genetic Counselors in Cardiac Care.

Recent advances in genetic testing for heritable cardiac diseases have led to an increasing involvement of the genetic counselor in cardiology practice. We present a series of cases collected from a nationwide query of genetics professionals regarding issues related to cost and utilization of genetic testing. Three themes emerged across cases: (1) choosing the most appropriate genetic test, (2) choosing the best person to test, and (3) interpreting results accurately. These cases demonstrate that involvement of a genetic counselor throughout the evaluation, diagnosis, and continuing management of individuals and families with inherited cardiovascular conditions helps to promote the efficient use of healthcare dollars.

Outcomes of genetic evaluation for hereditary cancer syndromes in unaffected individuals.

Genetic testing (GT) for inherited cancer predisposition is most informative when initiated in individuals with cancer, thus standard practice recommends GT start in an affected individual. This strategy can be frustrating for unaffected consultands and providers. Retrospective review of cases was performed to compare outcomes of testing the unaffected consultand and recommending that testing start in an affected relative. Records from cancer-free consultands (N = 101), presenting to the University of Michigan Cancer Genetics Clinic between 6/1/2011 and 12/30/2011 were reviewed. All genetics records for these consultands were reviewed through 3/31/2013 for GT recommendations (117 total). The unaffected consultand was offered testing in 14.5 % of cases, testing was completed in 64.7 % of these with one mutation identified. Of consultands tested initially, 70.5 % received cancer-screening recommendations based on family history and test results. Testing was recommended to start in an affected family member in 30.7 % of cases. Fifty percent returned to clinic with information on an affected family member; 83.3 % documented that their family member underwent GT with one mutation identified. Consultands reported the affected family member refused testing in 22.2 % and two of these consultands subsequently pursued GT, identifying one mutation. Fifty percent of cases where testing the family member first was recommended were lost to follow-up with 66.6 % of these never given cancer-screening recommendations. Cancer genetic risk evaluation of healthy consultands should consider the option of pursuing GT in the unaffected consultand and should implement a plan for tailored risk management in the absence of informative genetic evaluation within the family.

Screening for germline mismatch repair mutations following diagnosis of sebaceous neoplasm.

IMPORTANCE Sebaceous neoplasms (SNs) define the Muir-Torre syndrome variant of Lynch syndrome (LS), which is associated with increased risk for colon and other cancers necessitating earlier and more frequent screening to reduce morbidity and mortality.Immunohistochemical (IHC) staining for mismatch repair (MMR) proteins in SNs can be used to screen for LS, but data on subsequent germline genetic testing to confirm LS diagnosis are limited.OBJECTIVE To characterize the utility of IHC screening of SNs in identification of germline MMR mutations confirming LS.DESIGN, SETTING, AND PARTICIPANTS Retrospective study at 2 academic cancer centers of 86 adult patients referred for clinical genetics evaluation after diagnosis of SN.MAIN OUTCOMES AND MEASURES Results of tumor IHC testing and germline genetic testing were reviewed to determine positive predictive value and sensitivity of IHC testing in diagnosis of LS. Clinical variables, including age at diagnosis of SN, clinical diagnostic criteria for LS and Muir-Torre syndrome, and family history characteristics were compared between mutation carriers and noncarriers.RESULTS Of 86 patients with SNs, 25 (29%) had germline MMR mutations confirming LS.Among 77 patients with IHC testing on SNs, 38 (49%) had loss of staining of 1 or more MMR proteins and 14 had germline MMR mutations. Immunohistochemical analysis correctly identified 13 of 16 MMR mutation carriers, corresponding to 81% sensitivity. Ten of 12 patients(83%) with more than 1 SN had MMR mutations. Fifty-two percent of MMR mutation carriers did not meet clinical diagnostic criteria for LS, and 11 of 25 (44%) did not meet the clinical definition of Muir-Torre syndrome. CONCLUSIONS AND RELEVANCE Immunohistochemical screening of SNs is effective in identifying patients with germline MMR mutations and can be used as a first-line test when LSis suspected. Abnormal IHC results, including absence of MSH2, are not diagnostic of LS and should be interpreted cautiously in conjunction with family history and germline genetic testing. Use of family history to select patients for IHC screening has substantial limitations,suggesting that universal IHC screening of SNs merits further study. Clinical genetics evaluation is warranted for patients with abnormal IHC test results, normal IHC test results with personal or family history of other LS-associated neoplasms, and/or multiple SNs.

The clinical phenotype of SDHC-associated hereditary paraganglioma syndrome (PGL3).

CONTEXT: Mutations in the genes encoding subunits of the succinate dehydrogenase complex cause hereditary paraganglioma syndromes. Although the phenotypes associated with the more commonly mutated genes, SDHB and SDHD, are well described, less is known about SDHC-associated paragangliomas. OBJECTIVE: To describe functionality, penetrance, number of primary tumors, biological behavior, and location of paragangliomas associated with SDHC mutations. DESIGN: Families with an SDHC mutation were identified through a large cancer genetics registry. A retrospective chart review was conducted with a focus on patient and tumor characteristics. In addition, clinical reports on SDHC-related paragangliomas were identified in the medical literature to further define the phenotype and compare findings. SETTING: A cancer genetics clinic and registry at a tertiary referral center. PATIENTS: Eight index patients with SDHC-related paraganglioma were identified. RESULTS: Three of the eight index patients had mediastinal paraganglioma and four of the eight patients had more than one paraganglioma. Interestingly, the index patients were the only affected individuals in all families. When combining these index cases with reported cases in the medical literature, the mediastinum is the second most common location for SDHC-related paraganglioma (10% of all tumors), occurring in up to 13% of patients. CONCLUSIONS: Our findings suggest that thoracic paragangliomas are common in patients with SDHC mutations, and imaging of this area should be included in surveillance of mutation carriers. In addition, the absence of paragangliomas among at-risk relatives of SDHC mutation carriers suggests a less penetrant phenotype as compared to SDHB and SDHD mutations.

Identification of genetic counseling service delivery models in practice: a report from the NSGC Service Delivery Model Task Force.

Increasing demand for genetic services has resulted in the need to evaluate current service delivery models (SDMs) and consider approaches that improve access to and efficiency of genetic counseling (GC). This study aimed to describe SDMs currently used by the GC community. The NSGC membership was surveyed regarding the use of four SDMs: in-person GC, telephone GC, group GC, and telegenetics GC. Variables related to access and components of use were also surveyed, including: appointment availability, time-per-patient, number of patients seen, billing, and geographic accessiblity. Seven hundred one usable responses were received. Of these, 54.7 % reported using an in-person SDM exclusively. The remainder (45.3 %) reported using multiple SDMs. Telephone, group and telegenetics GC were used often or always by 8.0 %, 3.2 % and 2.2 % of respondents, respectively. Those using an in-person SDM reported the ability to see the highest number of patients per week (p < 0.0001) and were the most likely to bill in some manner (p < 0.0001). Those using telegenetic and telephone GC served patients who lived the furthest away, with 48.3 % and 35.8 %% respectively providing GC to patients who live >4 h away. This study shows that genetic counselors are incorporating SDMs other than traditional in-person genetic counseling, and are utilizing more than one model. These adaptations show a trend toward shorter wait time and shorter length of appointments. Further study is indicated to analyze benefits and limitations of each individual model and factors influencing the choice to adopt particular models into practice.

10 rare tumors that warrant a genetics referral.

The number of described cancer susceptibility syndromes continues to grow, as does our knowledge on how to manage these syndromes with the aim of early detection and cancer prevention. Oncologists now have greater responsibility to recognize patterns of cancer that warrant referral for a genetics consultation. While some patterns of common cancers are easy to recognize as related to hereditary cancer syndromes, there are a number of rare tumors that are highly associated with cancer syndromes yet are often overlooked given their infrequency. We present a review of ten rare tumors that are strongly associated with hereditary cancer predisposition syndromes: adrenocortical carcinoma, carcinoid tumors, diffuse gastric cancer, fallopian tube/primary peritoneal cancer, leiomyosarcoma, medullary thyroid cancer, paraganglioma/pheochromocytoma, renal cell carcinoma of chromophobe, hybrid oncocytoic, or oncocytoma histology, sebaceous carcinoma, and sex cord tumors with annular tubules. This review will serve as a guide for oncologists to assist in the recognition of rare tumors that warrant referral for a genetic consultation.

Report from the National Society of Genetic Counselors service delivery model task force: a proposal to define models, components, and modes of referral.

The Service Delivery Model Task Force (SDMTF) was appointed in 2009 by the leadership of the National Society of Genetic Counselors (NSGC) with a charge to research and assess the capacity of all existing service delivery models to improve access to genetic counseling services in the context of increasing demand for genetic testing and counseling. In approaching this charge, the SDMTF found that there were varying interpretations of what was meant by "service delivery models" and the group held extensive discussions about current practices to arrive at consensus of proposed definitions for current genetic service delivery models, modes of referral and components of service delivery. The major goal of these proposed definitions is to allow for conversations to begin to address the charge to the committee. We propose that current models of service delivery can be defined by: 1) the methods in which genetic counseling services are delivered (In-person, Telephone, Group and Telegenetics), 2) the way they are accessed by patients (Traditional referral, Tandem, Triage, Rescue and Self-referral) and 3) the variable components that depend upon multiple factors unique to each service setting. This report by the SDMTF provides a starting point whereby standardized terminology can be used in future studies that assess the effectiveness of these described models to overcome barriers to access to genetic counseling services.

Clinical use of the Surgeon General's "My Family Health Portrait" (MFHP) tool: opinions of future health care providers.

This study examined medical students' and house officers' opinions about the Surgeon General's "My Family Health Portrait" (MFHP) tool. Participants used the tool and were surveyed about tool mechanics, potential clinical uses, and barriers. None of the 97 participants had previously used this tool. The average time to enter a family history was 15 min (range 3 to 45 min). Participants agreed or strongly agreed that the MFHP tool is understandable (98%), easy to use (93%), and suitable for general public use (84%). Sixty-seven percent would encourage their patients to use the tool; 39% would ensure staff assistance. Participants would use the tool to identify patients at increased risk for disease (86%), record family history in the medical chart (84%), recommend preventive health behaviors (80%), and refer to genetics services (72%). Concerns about use of the tool included patient access, information accuracy, technical challenges, and the need for physician education on interpreting family history information.

AXIN2-associated autosomal dominant ectodermal dysplasia and neoplastic syndrome.

We describe a family with a novel, inherited AXIN2 mutation (c.1989G>A) segregating in an autosomal dominant pattern with oligodontia and variable other findings including colonic polyposis, gastric polyps, a mild ectodermal dysplasia phenotype with sparse hair and eyebrows, and early onset colorectal and breast cancers. This novel mutation predicts p.Trp663X, which is a truncated protein that is missing the last three exons, including the DIX (Disheveled and AXIN interacting) domain. This nonsense mutation is predicted to destroy the inhibitory action of AXIN2 on WNT signaling. Previous authors have described an unrelated family with autosomal dominant oligodontia and a variable colorectal phenotype segregating with a nonsense mutation of AXIN2, as well as a frameshift AXIN2 mutation in an unrelated individual with oligodontia. Our report provides additional evidence supporting an autosomal dominant AXIN2-associated ectodermal dysplasia and neoplastic syndrome.

Diagnosis and management of hereditary paraganglioma syndrome due to the F933>X67 SDHD mutation.

BACKGROUND: The hereditary paraganglioma syndromes (PGLs) are autosomal dominant conditions with an increased risk for tumors of the sympathetic and parasympathetic neuroendocrine systems. The recognition of patients with hereditary PGL and identification of the responsible gene are important for the management of index patients and family members. METHODS: We present the clinical, radiological, biochemical, and family history findings of a 15-year-old boy patient with a glomus vagale versus glomus jugulare tumor. RESULTS: Evaluation of the family history and the patient's history led to the identification of a familial succinate dehydrogenase subunit D (SDHD) gene mutation (F933>X67), consistent with a diagnosis of hereditary PGL1. Although this family had all head and neck tumors, this SDHD mutation has previously been described in a family with primarily functional pheochromocytomas. CONCLUSIONS: This case report highlights the variable expressivity of a single mutation in SDHD, (F933>X67). Careful and comprehensive screening is warranted for individuals at risk.

Using the common sense model to understand perceived cancer risk in individuals testing for BRCA1/2 mutations.

The common sense model posits that individuals' understanding of illness is based upon somatic symptoms and life experiences and thus may differ significantly from the biomedical view of illness. The current study used the common sense model to understand cancer risk perceptions in 99 individuals testing for BRCA1/2 mutations. Specifically, we examined change from post-counseling to post-result in (1) absolute risk (risk of developing cancer in one's lifetime) and (2) comparative risk (risk relative to the general population). Results indicated that absolute risk showed a trend such that those with a personal history of cancer receiving uninformative negative results reported decreased absolute risk. Further, individuals receiving uninformative negative results reported decreased comparative risk. Those with no personal cancer history receiving informative negative results did not decrease in risk over time nor did their risk differ from those with a personal cancer history, evidencing unrealistic pessimism regarding their risk of cancer. The reasons provided for individuals' risk perceptions could be classified in terms of attributes of the common sense model and included the: (1) causes of cancer (e.g. family history, mutation status); (2) control or cure of cancer through health behaviors and/or surgery; and (3) perceived timeline for developing cancer (e.g. time left in life to develop cancer). We conclude that key to developing interventions to improve understanding of cancer risk and promoting effective cancer control mechanisms is an understanding of the specific reasons underlying individuals' perceptions of cancer risk.

The decision to test in women receiving genetic counseling for BRCA1 and BRCA2 mutations.

Functions of genetic counseling include provision of risk information and provision of support in an effort to assist with decision making. This study examines (1) the relationship among intentions to test, self-reported provision of blood sample, and receipt of test results; (2) the impact of genetic counseling on distress specific to gene status, perceived risk of developing breast and ovarian cancer in the context having BRCA1/2 mutations (mutations predisposing to increased risk of breast-ovarian cancer), and perceived risk factors for breast cancer; and (3) the clinical profile of those receiving/not receiving results. Intentions to test for BRCA1/2 mutations, self-reported provision of blood sample immediately after counseling, and receipt of test results were statistically different but highly correlated, and intentions to test increased from pre- to postcounseling. A repeated measures ANOVA found distress specific to gene status and perceived risk factors decreased from pre- to postcounseling. Further, two clinical profiles of consultands emerged: (1) those receiving results with change in intentions to test having lower levels of distress and (2) those not receiving results and those receiving results with no change in intentions to test with higher levels of distress. Our findings are consistent with the function of genetic counseling-to provide information and support to those with familial cancer, as well as to assist in decision making. The provision of support is important as distress specific to gene status may impede flexible decision making about genetic testing.
