Genes affected
CAPN3 (HGNC:1480): (calpain 3) Calpain, a heterodimer consisting of a large and a small subunit, is a major intracellular protease, although its function has not been well established. This gene encodes a muscle-specific member of the calpain large subunit family that specifically binds to titin. Mutations in this gene are associated with limb-girdle muscular dystrophies type 2A. Alternate promoters and alternative splicing result in multiple transcript variants encoding different isoforms and some variants are ubiquitously expressed. [provided by RefSeq, Jul 2008]

Autosomal recessive limb-girdle muscular dystrophy type 2A Pathogenic:2
Nov 15, 2024
Labcorp Genetics (formerly Invitae), Labcorp
Significance: Pathogenic
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 82 of the CAPN3 protein (p.Pro82Leu). This variant is present in population databases (no rsID available, gnomAD 0.003%). This missense change has been observed in individual(s) with autosomal recessive limb-girdle muscular dystrophy (PMID: 12461690, 12890817, 15221789, 15351423, 16100770, 16141003, 16372320, 17157502, 20635405, 25135358, 26886200, 27447704). ClinVar contains an entry for this variant (Variation ID: 282783). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt CAPN3 protein function with a negative predictive value of 80%. For these reasons, this variant has been classified as Pathogenic. -
