Genes affected
LMNA (HGNC:6636): (lamin A/C) The protein encoded by this gene is part of the nuclear lamina, 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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineMar 02, 2012Variant classified as Uncertain Significance - Favor Benign. The *6G>A variant ( LMNA) has not been reported in the literature nor previously identified by our l aboratory. This variant occurs in the 3' untranslated region (3' UTR) and does n ot affect the coding sequence of the gene. Although this region can contain elem ents that regulate mRNA, there is no obvious predicted effect of this variant an d no other pathogenic variants have been reported in the 3' UTR region of the LM NA gene. In summary, the clinical significance of this variant cannot be determi ned at this time. -
Primary dilated cardiomyopathy Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAll of Us Research Program, National Institutes of HealthJan 11, 2024This variant is located in the 3' untranslated region of the LMNA gene. To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with cardiovascular disorders in the literature. This variant has been identified in 8/282412 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -
