LMNA and Emery-Dreifuss muscular dystrophy: Mutations in LMNA produce an intriguingly diverse spectrum of diseases including muscular dystrophies (Emery-Dreifuss muscular dystrophy, limb-girdle muscular dystrophy type 1B), neuropathy (Charcot-Marie-Tooth disease type 2), dilated cardiomyopathy with conduction system disease, familial partial lipodystrophy (s.c. fat loss and diabetes), mandibuloacral dysplasia (skeletal malformations and lipodystrophy), atypical Werner's syndrome, and Hutchinson-Gilford progeria syndrome(precocious aging syndromes) [15-19].
