Genomic Autopsy Finds Cardiac Variants in Young, Sudden Death Patients
Postmortem genetic testing identified pathogenic/likely pathogenic (P/LP) cardiac genetic variants in arrhythmia or cardiomyopathy genes in approximately 13% of young individuals with sudden death, according to a study published in JAMA Cardiology. Researchers of this study sought to assess both the genotypic and phenotypic risk of sudden death in a diverse cohort of young decedents and their families. The study comprised 103 decedents (mean age at death, 23 years), their surviving family members, as well as 140 sex- and genetic ancestry–matched controls. “Whole-genome sequencing effectively identified P/LP variants in cases of sudden death in young individuals, implicating both arrhythmia and cardiomyopathy genes,” the researchers concluded.
