A new clinical condition linked to a novel mutation in lamins A and C with generalized lipoatrophy, insulin-resistant diabetes, disseminated leukomelanodermic papules, liver steatosis, and cardiomyopathy.

Abstract excerpt

A-Type lamins, arising from the LMNA gene, are intermediate filaments proteins that belong to the lamina, a ubiquitous nuclear network. Naturally occurring mutations in these proteins have been shown to be responsible for several distinct diseases that display skeletal and/or cardiac muscle or peripheral nerve involvement. These include familial partial lipodystrophy of the Dunnigan type and the mandibuloacral...
