laminopathy

(redirected from Nuclear envelopathies)

laminopathy

A generic term for any enzymopathy caused by mutations of genes that encode lamins, which form the nuclear lamina. Lamins are intermediate filament proteins responsible for the molecular scaffolding under the nuclear membrane which attach to the membrane by farnesylation, a process in which hydrophobic lipid molecules are linked to a protein of interest (here, lamin A/C and lamin B).
 
Clinical findings
Muscular dystrophy, lipodystrophy, diabetes, dermopathy, neuropathy, leukodystrophy, progeria.
 
Examples
Charcot-Marie-Tooth disorder type 2B1, childhood progeria syndrome (Hutchinson-Gilford syndrome), dilated cardiomyopathy, Emery-Dreifuss muscular dystrophy type 2, familial partial lipodystrophy, limb-girdle muscular dystrophy type 1B,  mandibuloacral dysplasia, some cases of Werner syndrome.

laminopathy

(lă-mĭn-ŏp′ă-thē)
