We know of no information on the frequency and clinical genetics of familial DCM in Africa.12 Our aims were: (i) to describe the frequency of familial DCM in patients who were diagnosed with DCM and followed up in a cardiomyopathy clinic at the Cardiac Clinic, Groote Schuur Hospital (GSH), Cape Town, from 1 February 1996 to 31 December 2009; (ii) to determine, through pedigree analysis, the likely modes of inheritance of familial DCM in this cohort; and (iii) to address the implications of the findings for the clinical evaluation of patients with unexplained DCM.
