GeneDx RCV000481092 SCV000570408 likely benign not provided 2020-06-08 criteria provided, single submitter clinical testing Not observed in large population cohorts (Lek et al., 2016); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
Invitae RCV001851202 SCV002211343 uncertain significance Autosomal recessive limb-girdle muscular dystrophy type 2A 2022-10-05 criteria provided, single submitter clinical testing In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. 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 tolerated. ClinVar contains an entry for this variant (Variation ID: 421264). This missense change has been observed in individual(s) with autosomal recessive CAPN3-related conditions (PMID: 33337384). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 271 of the CAPN3 protein (p.Asn271Lys).
