In recent years, there has been a considerable influx of publications assessing the penetrance pathogenic variants associated with monogenic diseases dominant inheritance. As large and diverse groups have sequenced, it become clear that incomplete is common to most hereditary diseases, as numerous molecular, genetic, or environmental factors can cause clinical diversity among carriers same variant. this review, we discuss some these focus on existing approaches estimating penetrance, depending data available their application different sets. We also list currently large-scale sets estimates.

Abstract Hypertrophic cardiomyopathy (HCM) is a common hereditary condition affecting approximately 1 in 500 adults. It characterized by marked clinical heterogeneity with individuals experiencing minimal to no symptoms, while others may have more severe outcomes including heart failure and sudden cardiac death. Genetic testing for HCM increasingly available due advances DNA sequencing technologies reduced costs. While diagnosis of well‐supported indication genetic counseling, incorporation services into the setting often limited outside expert centers. As counseling become accessible convenient, optimal integration genomic data care should be instituted, delivery via counseling. Drawing on recommendations from recent disease guidelines systematic evidence reviews, we highlight key This practice resource provides comprehensive framework guide healthcare providers process test selection, variant classification, cascade evaluation HCM.

Precision medicine, which among other aspects includes an individual's genomic data in diagnosis and management, has become the standard‐of‐care for Mendelian cardiovascular disease (CVD). However, early identification management of asymptomatic patients with potentially lethal manageable CVD through screening, is promise precision health, remains unsolved challenge. The reduced costs sequencing have enabled creation biobanks containing in‐depth genetic health information, facilitated understanding variation, penetrance, expressivity, moving us closer to genotype‐first screening individuals CVD. This approach could transform care by diagnostic refinement facilitating prevention or therapeutic interventions. Yet, potential benefits must be weighed against risks, include evolving variant pathogenicity assertion variants low penetrance; costly, stressful, inappropriate evaluations; negative psychological impact; disqualification employment competitive sports; denial insurance. Furthermore, natural history often unpredictable, making those who will benefit from preventive measures a priority. Currently, there insufficient evidence that population‐based can reduce adverse outcomes at reasonable cost extent outweighs harms true‐positive false‐positive results. Besides technical, clinical, financial burdens, ethical legal pose unprecedented challenges. review highlights key developments field approaches summarizes challenges solutions pave way implementing this clinical care.

Dilated cardiomyopathy (DCM) is characterized by reduced systolic function and cardiac dilation. Cases without an identified secondary cause are classified as idiopathic dilated (IDC). Over the last 35 years, many cases of IDC have increasingly been recognized to be genetic in etiology with a core set definitively causal genes up 40% cases. While over 200 associated DCM, evidence supporting pathogenicity for most remains limited. Further, rapid advances sequencing bioinformatics recently revealed complex spectrum ranging from monogenic polygenic DCM. These also led discovery modifier variants forms DCM (e.g., alcohol-induced cardiomyopathy).
