Shared Genetic Vulnerability: Polygenic and Monogenic Contributions to Peripartum, Alcohol-Induced, and Cancer Therapy–Related Cardiomyopathies

A large multi-cohort genetic analysis shows that both rare monogenic variants and a high polygenic score for dilated cardiomyopathy (DCM) are enriched in peripartum, alcohol-induced, and cancer therapy–related cardiomyopathies, supporting a shared genetic susceptibility unmasked by diverse environmental stressors.

Common, Rare and Somatic Genetic Drivers Together Double 5‑Year Atrial Fibrillation Risk: Toward an Integrated Genomic Model (IGM‑AF)

A UK Biobank whole‑genome study finds polygenic, rare monogenic, and somatic (CHIP) variants each independently associate with incident atrial fibrillation (AF); combined genomic profiling plus clinical risk (CHARGE‑AF) improves discrimination (C=0.80) and reclassification.
