A recent report of a Saudi DCM family with no additional skin/hair features carrying a homozygous missense variant in DSP (c.1459A>G, p.N487D) also in the SRD [12] further supports the pathogenicity of the T356M variant in our family without the cutaneous manifestations typically seen with recessive genotypes. Here, DSP is linked to familial dilated cardiomyopathy.
