Beyond these classical sarcomeric mutations, MYH7 variants are also implicated in 40% of congenital HCM cases, and both MYH7 and MYBPC3 have been linked to other cardiomyopathies such as dilated cardiomyopathy (DCM) and left ventricular non-compaction (LVNC). The gene discussed is MYH7; the disease is left ventricular noncompaction.
