Curiously, another DCM patient from the same cohort harbored a variant in an enhancer region that regulates multiple genes such as Unc-13 homolog D (UNC13D), WW domain binding protein 2 (WBP2), SAP30 binding protein (SAP30BP) and Tripartite motif containing 65 (TRIM65). Here, UNC13D is linked to familial dilated cardiomyopathy.
