LMNA(redirected from lamin A/C-like 1)
LMNAA gene on chromosome 1q22 that encodes lamin A/C, a protein highly conserved in evolution that forms part of the two-dimensional matrix of proteins located next to the inner nuclear membrane. Lamins are involved in providing nuclear stability and chromatin structure, and in gene expression.
LMNA mutations cause the so-called laminopathies—e.g., Charcot-Marie-Tooth disease type 2B1, progeria (Hutchinson-Gilford syndrome), dilated cardiomyopathy, Emery-Dreifuss muscular dystrophy type 2, familial partial lipodystrophy, limb-girdle muscular dystrophy type 1B, mandibuloacral dysplasia, and some cases of Werner syndrome.
