The generation of the AD genetic cohort was limited by a shortage of published articles that assessed large DCM patient cohorts on a gene-specific level, which led to the absence of patients with TNNC1 and SCN5A variants in our generated cohort and prevented the comparison of sex ratios at the gene level for many DCM genes (eg, BAG3, DSP). The gene discussed is SCN5A; the disease is familial dilated cardiomyopathy.
