The locus at chromosome 5q31 carrying the non-coding steroid receptor RNA activator (SRA1) as well as human leukocyte antigen (HLA) complex group 22 (HCG22) at chromosome 6p21 have been significantly associated with dilated cardiomyopathy (DCM) [17], [18]. Here, HCG22 is linked to dilated cardiomyopathy.
