In addition to the known missense variant (rs2234962) in the BAG3 locus for dilated cardiomyopathy, we identify deleterious or damaging protein-coding variants in genes SYNPO2L, ERBB2, and STARD3 in strong LD with sentinel SNPs (LD R2 > 0.8). This evidence concerns the gene STARD3 and dilated cardiomyopathy.
