laminopathy(redirected from Nuclear envelopathies)
laminopathyA 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).
