RESUMO

Germline pathogenic variants in DICER1 predispose individuals to develop a variety of benign and malignant tumors. Accurate variant curation and classification is essential for reliable diagnosis of DICER1-related tumor predisposition and identification of individuals who may benefit from surveillance. Since 2015, most labs have followed the American College of Medical Genetics and Genomics and the Association for Molecular Pathology (ACMG/AMP) sequence variant classification guidelines for DICER1 germline variant curation. However, these general guidelines lack gene-specific nuances and leave room for subjectivity. Consequently, a group of DICER1 experts joined ClinGen to form the DICER1 and miRNA-Processing Genes Variant Curation Expert Panel (VCEP), to create DICER1- specific ACMG/AMP guidelines for germline variant curation. The VCEP followed the FDA-approved ClinGen protocol for adapting and piloting these guidelines. A diverse set of 40 DICER1 variants were selected for piloting, including 14 known Pathogenic/Likely Pathogenic (P/LP) variants, 12 known Benign/Likely Benign (B/LB) variants, and 14 variants classified as variants of uncertain significance (VUS) or with conflicting interpretations in ClinVar. Clinically meaningful classifications (i.e., P, LP, LB, or B) were achieved for 82.5% (33/40) of the pilot variants, with 100% concordance among the known P/LP and known B/LB variants. Half of the VUS or conflicting variants were resolved with four variants classified as LB and three as LP. These results demonstrate that the DICER1-specific guidelines for germline variant curation effectively classify known pathogenic and benign variants while reducing the frequency of uncertain classifications. Individuals and labs curating DICER1 variants should consider adopting this classification framework to encourage consistency and improve objectivity.

RESUMO

Polygenic risk scores (PRS) have potential to improve health care by identifying individuals that have elevated risk for common complex conditions. Use of PRS in clinical practice, however, requires careful assessment of the needs and capabilities of patients, providers, and health care systems. The electronic Medical Records and Genomics (eMERGE) network is conducting a collaborative study which will return PRS to 25,000 pediatric and adult participants. All participants will receive a risk report, potentially classifying them as high risk (∼2-10% per condition) for 1 or more of 10 conditions based on PRS. The study population is enriched by participants from racial and ethnic minority populations, underserved populations, and populations who experience poorer medical outcomes. All 10 eMERGE clinical sites conducted focus groups, interviews, and/or surveys to understand educational needs among key stakeholders-participants, providers, and/or study staff. Together, these studies highlighted the need for tools that address the perceived benefit/value of PRS, types of education/support needed, accessibility, and PRS-related knowledge and understanding. Based on findings from these preliminary studies, the network harmonized training initiatives and formal/informal educational resources. This paper summarizes eMERGE's collective approach to assessing educational needs and developing educational approaches for primary stakeholders. It discusses challenges encountered and solutions provided.

RESUMO

BACKGROUND & AIMS: Genetic variants affecting liver disease risk vary among racial and ethnic groups. Hispanics/Latinos in the United States have a high prevalence of PNPLA3 I148M, which increases liver disease risk, and a low prevalence of HSD17B13 predicted loss-of-function (pLoF) variants, which reduce risk. Less is known about the prevalence of liver disease-associated variants among Hispanic/Latino subpopulations defined by country of origin and genetic ancestry. We evaluated the prevalence of HSD17B13 pLoF variants and PNPLA3 I148M, and their associations with quantitative liver phenotypes in Hispanic/Latino participants from an electronic health record-linked biobank in New York City. METHODS: This study included 8739 adult Hispanic/Latino participants of the BioMe biobank with genotyping and exome sequencing data. We estimated the prevalence of Hispanic/Latino individuals harboring HSD17B13 and PNPLA3 variants, stratified by genetic ancestry, and performed association analyses between variants and liver enzymes and Fibrosis-4 (FIB-4) scores. RESULTS: Individuals with ancestry from Ecuador and Mexico had the lowest frequency of HSD17B13 pLoF variants (10%/7%) and the highest frequency of PNPLA3 I148M (54%/65%). These ancestry groups had the highest outpatient alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, and the largest proportion of individuals with a FIB-4 score greater than 2.67. HSD17B13 pLoF variants were associated with reduced ALT level (P = .002), AST level (P < .001), and FIB-4 score (P = .045). PNPLA3 I148M was associated with increased ALT level, AST level, and FIB-4 score (P < .001 for all). HSD17B13 pLoF variants mitigated the increase in ALT conferred by PNPLA3 I148M (P = .006). CONCLUSIONS: Variation in HSD17B13 and PNPLA3 variants across genetic ancestry groups may contribute to differential risk for liver fibrosis among Hispanic/Latino individuals.

RESUMO

Genetic counseling for patients who are pursuing genetic testing in the absence of a medical indication, referred to as elective genomic testing (EGT), is becoming more common. This type of testing has the potential to detect genetic conditions before there is a significant health impact permitting earlier management and/or treatment. Pre- and post-test counseling for EGT is similar to indication-based genetic testing. Both require a complete family and medical history when ordering a test or interpreting a result. However, EGT counseling has some special considerations including greater uncertainties around penetrance and clinical utility and a lack of published guidelines. While certain considerations in the selection of a high-quality genetic testing laboratory are universal, there are some considerations that are unique to the selection of a laboratory performing EGT. This practice resource intends to provide guidance for genetic counselors and other healthcare providers caring for adults seeking pre- or post-test counseling for EGT. Genetic counselors and other genetics trained healthcare providers are the ideal medical professionals to supply accurate information to individuals seeking counseling about EGT enabling them to make informed decisions about testing and follow-up.

RESUMO

Elective genetic testing (EGT) to identify disease risk in individuals who may or may not meet clinical criteria for testing is increasingly being offered in clinical practice. However, little is known about how EGT is currently implemented and how genetics professionals perceive this type of testing. We conducted a mixed-methods survey study to evaluate genetics professionals' perspectives and attitudes about EGT and describe the current landscape of EGT practices in the United States (U.S.) and Canada. Six clinical geneticists and 131 genetic counselors responded to the online survey, among whom 44% reported offering EGT in their practice. Over 84% of survey respondents agreed that EGT may improve health outcomes and understanding of genotype-phenotype correlations, and 85% agreed that potential risks include result misinterpretation and contribution to economic health disparities. Though most respondents felt comfortable providing pretest (77%) and post-test (86%) counseling for EGT, lack of provider resources (such as time and personnel) and prioritization of diagnostic testing were cited most frequently in free-text responses as reasons for not offering EGT. Of those offering EGT, 88% reported positive overall experiences. Qualitative analysis of open-ended questions identified benefits of EGT as expanding access to genetic testing, providing potential health benefits, and providing psychological benefits for patients. Disadvantages included prohibitive costs, limited clinical utility, and strain on resources. Overall, we found that genetics providers perceive both potential benefits and harms of EGT and that those offering this testing had generally positive experiences, although ethical reservations and practical limitations exist.

RESUMO

CDH1 pathogenic variants confer a markedly elevated lifetime risk of developing diffuse gastric cancer (DGC) and lobular breast cancer (LBC). The aim of this study was to evaluate the prevalence and clinical impact of CDH1 pathogenic variants in the unselected and ancestrally diverse BioMe Biobank. We evaluated exome sequence data from 30,223 adult BioMe participants to identify CDH1 positive individuals, defined as those harboring a variant previously classified as pathogenic or likely pathogenic or a predicted loss-of-function variant in CDH1. We reviewed electronic health records and BioMe enrollment surveys for personal and family history of malignancy and evidence of prior clinical genetic testing. Using a genomics-first approach, we identified 6 CDH1 positive individuals in BioMe (~ 1 in 5000). CDH1 positive individuals had a median age of 42 years (range 35-62 years), all were non-European by self-report, and one was female. None had evidence of either a personal or family history of DGC or LBC. Our findings suggest a low risk of DGC and LBC in unselected patients harboring a pathogenic variant in CDH1. Knowledge of CDH1-related cancer risk in individuals with no personal or family history may better inform surveillance and prophylactic measures.

RESUMO

OBJECTIVES: Up to 15% of pancreatic cancer is hereditary. We aim to study the prevalence of pathogenic germline variants (PGVs) in patients referred for genetic counseling with a family history (FH) of pancreatic cancer. METHODS: We performed a retrospective single institution cohort study of individuals who underwent cancer genetic counseling with a FH of pancreatic cancer. RESULTS: We identified 314 patients. Genetic testing was performed in 291 (92.7%) and 187 (59.6%) underwent expanded multigene panel testing. Fifty-four PGVs were found in 53 (16.9%) individuals; PGVs in BRCA1/2 (37%) were most common. Seventy-two variants of uncertain significance (VUS) were found in 58 (18.5%) individuals; VUS in ATM (16.7%) were the most common. Of the 112 (35.4%) with a first-degree family member with pancreatic cancer, 14 PGVs were identified in 14 (12.5%) individuals and 28 VUS were identified in 21 (18.8%) individuals. After genetic testing, 47 (15.0%) individuals met International Cancer of the Pancreas Screening criteria and 67 (21.3%) met American College of Gastroenterology criteria for pancreatic surveillance. CONCLUSIONS: Genetic testing of individuals with a FH of pancreatic cancer represents an opportunity to identify individuals who may be candidates for pancreatic surveillance.

RESUMO

Understanding population health disparities is an essential component of equitable precision health efforts. Epidemiology research often relies on definitions of race and ethnicity, but these population labels may not adequately capture disease burdens and environmental factors impacting specific sub-populations. Here, we propose a framework for repurposing data from electronic health records (EHRs) in concert with genomic data to explore the demographic ties that can impact disease burdens. Using data from a diverse biobank in New York City, we identified 17 communities sharing recent genetic ancestry. We observed 1,177 health outcomes that were statistically associated with a specific group and demonstrated significant differences in the segregation of genetic variants contributing to Mendelian diseases. We also demonstrated that fine-scale population structure can impact the prediction of complex disease risk within groups. This work reinforces the utility of linking genomic data to EHRs and provides a framework toward fine-scale monitoring of population health.

RESUMO

BACKGROUND: Population-based genomic screening has the predicted ability to reduce morbidity and mortality associated with medically actionable conditions. However, much research is needed to develop standards for genomic screening and to understand the perspectives of people offered this new testing modality. This is particularly true for non-European ancestry populations who are vastly underrepresented in genomic medicine research. Therefore, we implemented a pilot genomic screening program in the BioMe Biobank in New York City, where the majority of participants are of non-European ancestry. METHODS: We initiated genomic screening for well-established genes associated with hereditary breast and ovarian cancer syndrome (HBOC), Lynch syndrome (LS), and familial hypercholesterolemia (FH). We evaluated and included an additional gene (TTR) associated with hereditary transthyretin amyloidosis (hATTR), which has a common founder variant in African ancestry populations. We evaluated the characteristics of 74 participants who received results associated with these conditions. We also assessed the preferences of 7461 newly enrolled BioMe participants to receive genomic results. RESULTS: In the pilot genomic screening program, 74 consented participants received results related to HBOC (N = 26), LS (N = 6), FH (N = 8), and hATTR (N = 34). Thirty-three of 34 (97.1%) participants who received a result related to hATTR were self-reported African American/African (AA) or Hispanic/Latinx (HL), compared to 14 of 40 (35.0%) participants who received a result related to HBOC, LS, or FH. Among the 7461 participants enrolled after the BioMe protocol modification to allow the return of genomic results, 93.4% indicated that they would want to receive results. Younger participants, women, and HL participants were more likely to opt to receive results. CONCLUSIONS: The addition of TTR to a pilot genomic screening program meant that we returned results to a higher proportion of AA and HL participants, in comparison with genes traditionally included in genomic screening programs in the USA. We found that the majority of participants in a multi-ethnic biobank are interested in receiving genomic results for medically actionable conditions. These findings increase knowledge about the perspectives of diverse research participants on receiving genomic results and inform the broader implementation of genomic medicine in underrepresented patient populations.

RESUMO

The TTR V142I variant associated with hereditary transthyretin amyloidosis (hATTR) is present in up to 4% of African American (AA) and 1% of Hispanic/Latinx (HL) individuals and increases risk for heart failure. Delayed and missed diagnoses could potentiate health disparities in these populations. We evaluated whether population-based genomic screening could effectively identify individuals at risk for hATTR and prompt initiation of risk management. We identified participants of the BioMe Biobank in New York City who received TTR V142I results through a pilot genomic screening program. We performed a retrospective medical record review to evaluate for the presence hATTR-related systemic features, uptake of recommended follow-up, and short-term outcomes. Thirty-two AA (N = 17) and HL (N = 15) individuals received a TTR V142I result (median age 57, 81% female). None had a previous diagnosis of hATTR. Eighteen (56%) had hATTR-related systemic features, including 4 (13%) with heart failure, 10 (31%) with carpal tunnel syndrome, and 10 (31%) with spinal stenosis. Eighteen (56%) pursued follow-up with a cardiologist within 8 months. One person received a diagnosis of hATTR. Thus, we found that the majority of V142I-positive individuals had hATTR-related systemic features at the time of result disclosure, including well-described red flags. Genomic screening can help identify hATTR risk and guide management early on, avoiding potential delays in diagnosis and treatment.

RESUMO

PURPOSE: Limited data are available on the prevalence and clinical impact of Lynch syndrome (LS)-associated genomic variants in non-European ancestry populations. We identified and characterized individuals harboring LS-associated variants in the ancestrally diverse BioMe Biobank in New York City. PATIENTS AND METHODS: Exome sequence data from 30,223 adult BioMe participants were evaluated for pathogenic, likely pathogenic, and predicted loss-of-function variants in MLH1, MSH2, MSH6, and PMS2. Survey and electronic health record data from variant-positive individuals were reviewed for personal and family cancer histories. RESULTS: We identified 70 individuals (0.2%) harboring LS-associated variants in MLH1 (n = 12; 17%), MSH2 (n = 13; 19%), MSH6 (n = 16; 23%), and PMS2 (n = 29; 41%). The overall prevalence was 1 in 432, with higher prevalence among individuals of self-reported African ancestry (1 in 299) than among Hispanic/Latinx (1 in 654) or European (1 in 518) ancestries. Thirteen variant-positive individuals (19%) had a personal history, and 19 (27%) had a family history of an LS-related cancer. LS-related cancer rates were highest in individuals with MSH6 variants (31%) and lowest in those with PMS2 variants (7%). LS-associated variants were associated with increased risk of colorectal (odds ratio [OR], 5.0; P = .02) and endometrial (OR, 30.1; P = 8.5 × 10-9) cancers in BioMe. Only 2 variant-positive individuals (3%) had a documented diagnosis of LS. CONCLUSION: We found a higher prevalence of LS-associated variants among individuals of African ancestry in New York City. Although cancer risk is significantly increased among variant-positive individuals, the majority do not harbor a clinical diagnosis of LS, suggesting underrecognition of this disease.

RESUMO

PURPOSE: CTNNA1 is a potential diffuse gastric cancer risk gene, however CTNNA1 testing on multigene panel testing (MGPT) remains unstudied. METHODS: De-identified data from 151,425 individuals who underwent CTNNA1 testing at a commercial laboratory between October 2015 and July 2019 were reviewed. Tissue α-E-catenin immunohistochemistry was performed on CTNNA1 c.1351C>T (p.Arg451*) carriers. RESULTS: Fifty-two individuals (0.03% tested) had CTNNA1 loss-of-function (LOF) variants and 1057 individuals (0.7% tested) had a total of 302 distinct missense variants of uncertain significance. Detailed history was available on 33 CTNNA1 LOF carriers, with 21 unique CTNNA1 LOF variants. Four (12%) individuals had diffuse gastric cancer and 22 (67%) had breast cancer. Six (21%) and 24 (83%) of the 29 families reported a history of gastric or breast cancer, respectively. The CTNNA1 c.1351C>T nonsense variant was identified in three separate families with early-onset diffuse gastric cancer or breast cancer. Immunohistochemistry showed decreased α-E-catenin expression in gastric cancers. CONCLUSION: CTNNA1 LOF variants are detected on MGPT with a majority of these individuals having gastric or breast cancer. The overall risk of gastric cancer for CTNNA1 LOF carriers may be lower than expected. Given the uncertain phenotype and penetrance, management of individuals with CTNNA1 LOF variants remains challenging.

RESUMO

BACKGROUND: Pathogenic variants in BRCA1 and BRCA2 (BRCA1/2) lead to increased risk of breast, ovarian, and other cancers, but most variant-positive individuals in the general population are unaware of their risk, and little is known about prevalence in non-European populations. We investigated BRCA1/2 prevalence and impact in the electronic health record (EHR)-linked BioMe Biobank in New York City. METHODS: Exome sequence data from 30,223 adult BioMe participants were evaluated for pathogenic variants in BRCA1/2. Prevalence estimates were made in population groups defined by genetic ancestry and self-report. EHR data were used to evaluate clinical characteristics of variant-positive individuals. RESULTS: There were 218 (0.7%) individuals harboring expected pathogenic variants, resulting in an overall prevalence of 1 in 139. The highest prevalence was in individuals with Ashkenazi Jewish (AJ; 1 in 49), Filipino and other Southeast Asian (1 in 81), and non-AJ European (1 in 103) ancestry. Among 218 variant-positive individuals, 112 (51.4%) harbored known founder variants: 80 had AJ founder variants (BRCA1 c.5266dupC and c.68_69delAG, and BRCA2 c.5946delT), 8 had a Puerto Rican founder variant (BRCA2 c.3922G>T), and 24 had one of 19 other founder variants. Non-European populations were more likely to harbor BRCA1/2 variants that were not classified in ClinVar or that had uncertain or conflicting evidence for pathogenicity (uncertain/conflicting). Within mixed ancestry populations, such as Hispanic/Latinos with genetic ancestry from Africa, Europe, and the Americas, there was a strong correlation between the proportion of African genetic ancestry and the likelihood of harboring an uncertain/conflicting variant. Approximately 28% of variant-positive individuals had a personal history, and 45% had a personal or family history of BRCA1/2-associated cancers. Approximately 27% of variant-positive individuals had prior clinical genetic testing for BRCA1/2. However, individuals with AJ founder variants were twice as likely to have had a clinical test (39%) than those with other pathogenic variants (20%). CONCLUSIONS: These findings deepen our knowledge about BRCA1/2 variants and associated cancer risk in diverse populations, indicate a gap in knowledge about potential cancer-related variants in non-European populations, and suggest that genomic screening in diverse patient populations may be an effective tool to identify at-risk individuals.

RESUMO

INTRODUCTION: Colorectal cancer (CRC) is one of the leading causes of cancer death for both men and women in the United States. Several factors can increase one's risk of CRC, including a personal or family history of CRC, a diagnosis or family history of a hereditary colon cancer syndrome, or a diagnosis of chronic inflammatory bowel disease. The purpose of this project was to create a colorectal cancer registry (Co-Care) for individuals with a personal or family history of CRC, and those with disorders of the colon or rectum that are associated with an increased risk for developing CRC. Methods: To be eligible for the registry, patients either had a personal or family history of CRC, a diagnosis or family history of Lynch syndrome, familial adenomatous polyposis, or a diagnosis of Crohn's colitis or ulcerative colitis with dysplasia. Participants were recruited after seeing their gastroenterologist or genetic counselor, or after undergoing a full or partial colectomy at Mount Sinai Hospital in New York City. Eligible patients who agreed to participate were interviewed by a member of the research staff and asked a wide range of questions pertaining to CRC risk. RESULTS: A total of 224 patients were enrolled in the registry. Participants are mostly white, born in the United States, and married, with a bachelor's or graduate degree, reporting an annual household income of $100,000 or more. The largest portion have a family history of CRC (27.2%), and almost half of participants are of Jewish descent (46.2%) and have undergone full or partial colectomy (48.2%). More than half of participants have neither received genetic counseling (54.5%) nor undergone genetic testing (59.7%). Only 3.6% report that they currently smoke cigarettes, and 41.1% consume alcohol at least once per week. Lastly, 18.3%, 10.3%, and 27.7% of participants report that they currently take aspirin, folic acid/folate pills or tablets, or calcium pills/tablets, respectively. CONCLUSIONS: This registry can improve our understanding of CRC and related diseases, and be used to design future interventions related to disease risk, prognosis, and prevention of CRC.
