lamin B2

From NCBI Gene:

This gene encodes a B type nuclear lamin. The nuclear lamina consists of a two-dimensional matrix of proteins located next to the inner nuclear membrane. The lamin family of proteins make up the matrix and are highly conserved in evolution. During mitosis, the lamina matrix is reversibly disassembled as the lamin proteins are phosphorylated. Lamin proteins are thought to be involved in nuclear stability, chromatin structure and gene expression. Vertebrate lamins consist of two types, A and B. Mutations in this gene are associated with acquired partial lipodystrophy. [provided by RefSeq, May 2012]

From UniProt:

Lamins are components of the nuclear lamina, a fibrous layer on the nucleoplasmic side of the inner nuclear membrane, which is thought to provide a framework for the nuclear envelope and may also interact with chromatin.

  • Epilepsy, progressive myoclonic, 9
  • Acquired partial lipodystrophy

From UniProt:

Partial acquired lipodystrophy (APLD): A rare childhood disease characterized by loss of subcutaneous fat from the face and trunk. Fat deposition on the pelvic girdle and lower limbs is normal or excessive. Most frequently, onset between 5 and 15 years of age. Most affected subjects are females and some show no other abnormality, but many develop glomerulonephritis, diabetes mellitus, hyperlipidemia, and complement deficiency. Mental retardation in some cases. APLD is a sporadic disorder of unknown etiology. [MIM:608709]

Epilepsy, progressive myoclonic 9 (EPM9): An autosomal recessive form of progressive myoclonic epilepsy, a rare disease initially responsive to antiepileptic drugs which over time becomes refractory and can be associated with cognitive decline. EPM9 features include myoclonus, tonic-clonic seizures, ataxia, and psychomotor development. [MIM:616540]
