Mutations in the lamin A/C gene (LMNA) are associated with a collection of over ten diseases known as laminopathies, including but not restricted to dilated cardiomyopathy (DCM), Emery-Dreifuss muscular dystrophy (EDMD), restrictive dermopathy, familial partial lipodystrophy (FPLD), and premature ageing (OMIM # 150330). Here, LMNA is linked to Emery-Dreifuss muscular dystrophy.
