Invitae RCV000345099 SCV000645466 pathogenic Limb-girdle muscular dystrophy, type 2A 2017-04-18 criteria provided, single submitter clinical testing This sequence change replaces arginine with cysteine at codon 437 of the CAPN3 protein (p.Arg437Cys). The arginine residue is highly conserved and there is a large physicochemical difference between arginine and cysteine. This variant is present in population databases (rs777483913, ExAC 0.004%). This variant has been reported as homozygous or compound heterozygous with a second deleterious allele in several individuals affected with limb girdle muscular dystrophy, type 2A (PMID: 10330340, 27081656, 16141003, 15221789, 20044116, 18854869, 18563459, 26404900).  ClinVar contains an entry for this variant (Variation ID:285470). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies. For these reasons, this variant has been classified as Pathogenic.
