lamin A/C (LMNA) Homo sapiens 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. Alternative splicing results in multiple transcript variants. Mutations in this gene lead to several diseases: Emery-Dreifuss muscular dystrophy , familial partial lipodystrophy , limb girdle muscular dystrophy , dilated cardiomyopathy , Charcot-Marie-Tooth disease , and Hutchinson-Gilford progeria syndrome.
