Laminopathies are a diverse group of genetic disorders arising from mutations in LMNA gene encoding A-type lamins A & C, filament proteins of nuclear lamina/membrane of most somatic cells. The first-described laminopathies were
diseases of striated muscle such as autosomal-dominant Emery-Dreifuss muscular dystrophy (EDMD). The
life-threatening feature of EDMD is dilated cardiomyopathy with early conduction system abnormalities. LMNA
mutations have also been associated with cases of congenital muscular dystrophy (CMD) with heart involvement.
Some other diseases related to LMNA mutation are Limb-girdle muscular dystrophy, Heart-hand syndrome,
Dunnigan-type familial partial lipodystrophy, Mandibuloacral dysplasia, Hutchinson-Gilford progeria syndrome.
