Variant summary

Our verdict is Pathogenic. The variant received 14 ACMG points: 14P and 0B. PM1PM5PP3_ModeratePP5_Very_Strong

The NM_000070.3(CAPN3):c.640G>A(p.Gly214Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000483 in 1,613,778 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G214D) has been classified as Likely pathogenic.

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]

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 214 of the CAPN3 protein (p.Gly214Ser). This variant is present in population databases (rs369784333, gnomAD 0.02%). This missense change has been observed in individual(s) with autosomal recessive limb-girdle muscular dystrophy (PMID: 19556129, 25135358, 30919934). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 496915). 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. -

Collection Method:clinical testing

Variant summary: CAPN3 c.640G>A (p.Gly214Ser) results in a non-conservative amino acid change located in the Peptidase C2, calpain, catalytic domain of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 8.7e-05 in 251464 control chromosomes. This frequency is not significantly higher than expected for a pathogenic variant in CAPN3 causing Limb-Girdle Muscular Dystrophy, Autosomal Recessive (8.7e-05 vs 0.0032), allowing no conclusion about variant significance. c.640G>A has been reported in the literature in multiple individuals affected with Limb-Girdle Muscular Dystrophy, Autosomal Recessive. These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Six clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation (Pathogenic/likely pathogenic n=5, VUS n=1). Based on the evidence outlined above, the variant was classified as pathogenic. -
