We have analyzed the relationship between DCM and SNPs in the genes HSPB7, ZBTB17, and ACTC1. It has been shown that the T allele of ZBTB17 (rs10927875) and the ‘CT’ genotype are associated with DCM in a subgroup of patients within the Chinese population. Here, HSPB7 is linked to familial dilated cardiomyopathy.
