The GC Immersive: Patching the pipeline with genetic counseling experiences for all.

Genetic counseling graduate programs largely recommend that prospective applicants shadow or gain exposure to genetic counselors (GC) as a means of developing insight into the profession. However, prospective students have cited this need to shadow genetic counselors as harder to access in comparison to other prerequisites. The GC Immersive (GCI) at Color was created as a no-cost, remote, self-paced professional exploration program designed to provide resources and live interaction with a team of genetic counselors to increase accessibility to GC exposure and enhance the competitiveness of underrepresented GC candidates. The program design and curriculum were developed by a team of certified genetic counselors and a GC student in 2021 and is marketed to those who have one or more identities underrepresented in the GC field. In total, 287 individuals enrolled in the program in the first and second cycles, with 115 providing demographic information. The majority of enrollees identified as an underrepresented minority in GC in one or more identities, with individuals who are ethnic and/or racial minority (70%), first-generation college student (44%), lesbian, gay, transgender, queer, intersex, and/or asexual (LGBTQIA+) (27%), and disabled community (16%) reported as the most common identities. Most participants had never shadowed a GC (55%) prior to this course. Twenty-two percent of enrollees resided outside of the United States, representing 15 different countries. Of the 287 enrolled participants, 21 (7%) have completed the program, with the remaining participants having between 5 and 11 months to complete. All individuals who completed the program reported they felt better prepared to apply for a GC program. The general structure of this program can be replicated by any institution, as the program consists primarily of recorded content. Ongoing effort by genetic counselors is minimal and has the ability to provide GC experience to prospective applicants at great scale.

SARS-CoV-2 mRNA vaccine induced higher antibody affinity and IgG titers against variants of concern in post-partum vs non-post-partum women.

BACKGROUND: Limited knowledge exists in post-partum women regarding durability of SARS-CoV-2 vaccine-induced antibody responses and their neutralising ability against SARS-CoV-2 variants of concern (VOC). METHODS: We elucidated longitudinal mRNA vaccination-induced antibody profiles of 13 post-partum and 13 non-post-partum women (control). FINDINGS: The antibody neutralisation titres against SARS-CoV-2 WA-1 strain were comparable between post-partum and non-post-partum women and these levels were sustained up to four months post-second vaccination in both groups. However, neutralisation titers declined against several VOCs, including Beta and Delta. Higher antibody binding was observed against SARS-CoV-2 receptor-binding domain (RBD) mutants with key VOC amino acids when tested with post-second vaccination plasma from post-partum women compared with controls. Importantly, post-vaccination plasma antibody affinity against VOCs RBDs was significantly higher in post-partum women compared with controls. INTERPRETATION: This study demonstrates that there is a differential vaccination-induced immune responses in post-partum women compared with non-post-partum women, which could help inform future vaccination strategies for these groups. FUNDING: The antibody characterisation work described in this manuscript was supported by FDA's Medical Countermeasures Initiative (MCMi) grant #OCET 2021-1565 to S.K and intramural FDA-CBER COVID-19 supplemental funds.

Genetic counselor roles in the undiagnosed diseases network research study: Clinical care, collaboration, and curation.

Genetic counselors (GCs) are increasingly filling important positions on research study teams, but there is limited literature describing the roles of GCs in these settings. GCs on the Undiagnosed Diseases Network (UDN) study team serve in a variety of roles across the research network and provide an opportunity to better understand genetic counselor roles in research. To quantitatively characterize the tasks regularly performed and professional fulfillment derived from these tasks, two surveys were administered to UDN GCs in a stepwise fashion. Responses from the first, free-response survey elicited the scope of tasks which informed development of a second structured, multiple-select survey. In survey 2, respondents were asked to select which roles they performed. Across 19 respondents, roles in survey 2 received a total of 947 selections averaging approximately 10 selections per role. When asked to indicate what roles they performed, respondent selected a mean of 50 roles (range 22-70). Survey 2 data were analyzed via thematic coding of responses and hierarchical cluster analysis to identify patterns in responses. From the thematic analysis, 20 non-overlapping codes emerged in seven categories: clinical interaction and care, communication, curation, leadership, participant management, research, and team management. Three themes emerged from the categories that represented the roles of GCs in the UDN: clinical care, collaboration, and curation. Cluster analyses showed that responses were more similar among individuals at the same institution than between institutions. This study highlights the ways GCs apply their unique skill set in the context of a clinical translational research network. Additionally, findings from this study reinforce the wide applicability of core skills that are part of genetic counseling training. Clinical literacy, genomics expertise and analysis, interpersonal, psychosocial and counseling skills, education, professional practice skills, and an understanding of research processes make genetic counselors well suited for such roles and poised to positively impact research experiences and outcomes for participants.

Rare disease patient matchmaking: development and outcomes of an internet case-finding strategy in the Undiagnosed Diseases Network.

BACKGROUND: Although clinician, researcher, and patient resources for matchmaking exist, finding similar patients remains an obstacle for rare disease diagnosis. The goals of this study were to develop and test the effectiveness of an Internet case-finding strategy and identify factors associated with increased matching within a rare disease population. METHODS: Public web pages were created for consented participants. Matches made, time to each inquiry and match, and outcomes were recorded and analyzed using descriptive statistics. A Poisson regression model was run to identify characteristics associated with matches. RESULTS: 385 participants were referred to the project and 158 had pages posted. 579 inquiries were received; 89.0% were from the general public and 24.7% resulted in a match. 81.6% of pages received at least one inquiry and 15.0% had at least one patient match. Primary symptom category of neurology, diagnosis, gene page, and photo were associated with increased matches (p ≤ 0.05). CONCLUSIONS: This Internet case-finding strategy was of interest to patients, families, and clinicians, and similar patients were identified using this approach. Extending matchmaking efforts to the general public resulted in matches and suggests including this population in matchmaking activities can improve identification of similar patients.

Family genetic result communication in rare and undiagnosed disease communities: Understanding the practice.

Genetic results have implications not only for the individual, but also for their family members. Research on family communication of genetic results has primarily focused on families affected by adult-onset, dominant conditions as well as more common genetic conditions such as familial hypercholesterolemia, cardiomyopathies, and genetic hearing loss. This study therefore aimed to characterize genetic result communication in families with rare and undiagnosed conditions and identify factors that influence communication. One hundred and forty-two individuals who received a diagnosis from the Undiagnosed Diseases Network (UDN), a study focused on providing diagnoses to individuals with undiagnosed conditions, were eligible to complete a survey assessing genetic results communication. Survey items assessed if communication was discussed with healthcare providers, with whom participants communicated genetic testing, why they chose to communicate with these family members, and what information they communicated. All respondents (5 adult UDN participants, 38 parents/guardians of UDN participants, and 2 identifying as both) shared genetic results with at least one family member. Individuals who identified as both were considered exclusively adult participants for the purpose of these analyses. Adult participants and parents/guardians of participants reported high levels of understanding (96%), utility (96%), and comfort communicating genetic results (89%). Additionally, parents/guardians were more likely to disclose genetic results due to a general desire to share (60% of parents/guardians vs. 14% adult participants), while adult participants reported that they shared results to communicate risk to family members (86% of adult participants vs. 24% of parents/guardians). Many respondents did not recall discussing with a healthcare provider how (64%) or what (42%) to communicate about results. The results of this study provide insight into the practice of result communication by individuals with rare and previously undiagnosed conditions, which can ideally inform development of more effective counseling strategies and guidelines to aid family communication.

Missed diagnoses: Clinically relevant lessons learned through medical mysteries solved by the Undiagnosed Diseases Network.

BACKGROUND: Resources within the Undiagnosed Diseases Network (UDN), such as genome sequencing (GS) and model organisms aid in diagnosis and identification of new disease genes, but are currently difficult to access by clinical providers. While these resources do contribute to diagnoses in many cases, they are not always necessary to reach diagnostic resolution. The UDN experience has been that participants can also receive diagnoses through the thoughtful and customized application of approaches and resources that are readily available in clinical settings. METHODS: The UDN Genetic Counseling and Testing Working Group collected case vignettes that illustrated how clinically available methods resulted in diagnoses. The case vignettes were classified into three themes; phenotypic considerations, selection of genetic testing, and evaluating exome/GS variants and data. RESULTS: We present 12 participants that illustrate how clinical practices such as phenotype-driven genomic investigations, consideration of variable expressivity, selecting the relevant tissue of interest for testing, utilizing updated testing platforms, and recognition of alternate transcript nomenclature resulted in diagnoses. CONCLUSION: These examples demonstrate that when a diagnosis is elusive, an iterative patient-specific approach utilizing assessment options available to clinical providers may solve a portion of cases. However, this does require increased provider time commitment, a particular challenge in the current practice of genomics.

The importance of personalismo: Navigating obstacles in recruitment strategies for Spanish speakers in marginalized communities.

Recruitment obstacles with Spanish-speaking individuals and members of marginalized communities have been documented in the literature in narrative form, but quantitative data on effective strategies are limited. Within our research protocol assessing the impact of a storytelling intervention on knowledge and uptake of cell-free DNA (cfDNA) aneuploidy screening, three different recruitment strategies were trialed and enrollment rates were compared. Throughout the study, field notes were collected from observations in recruitment efforts. We demonstrate the effectiveness of language-concordant, personal interactions, and culturally tailored materials for recruitment of Spanish-speaking participants into genomic research studies. We also offer commentary on the experience of the researchers that provides insights to inform recruitment methods for marginalized communities.

Cases from the Undiagnosed Diseases Network: The continued value of counseling skills in a new genomic era.

The "diagnostic odyssey" is well known and described in genetic counseling literature. Studies addressing the psychological, emotional, and financial costs of not having a diagnosis have shown how it permeates the lives of patients and families. The Undiagnosed Diseases Network aims to end this odyssey by providing diagnoses to individuals with undiagnosed conditions through multidisciplinary evaluations, whole exome and genome sequencing, and basic science research. It also provides an opportunity to learn from patients and families and to better understand their journeys and the impact of receiving a diagnosis. Seven cases are presented that outline challenges that come from working with chronically undiagnosed and newly diagnosed patients in a time when sequencing for clinical diagnosis is rapidly increasing. They illuminate the emotional journey of patients and families searching for a diagnosis and the mental health problems, financial distress, and chaos that can accompany not having answers. They also illustrate the surprising reactions patients and families can have to receiving a diagnosis, including anger, grief, and disappointment. While the lessons learned from these families are not novel, new strategies are presented for handling these challenges in undiagnosed and ultra-rare populations, groups that will increase with the rise of clinical sequencing.
