Invitae RCV000674583 SCV001540818 pathogenic Autosomal recessive limb-girdle muscular dystrophy type 2E 2024-01-08 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 167 of the SGCB protein (p.Gly167Ser). This variant is present in population databases (rs779516489, gnomAD 0.006%). This missense change has been observed in individual(s) with SGCB-related conditions (PMID: 11166169, 25862795; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 558332). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SGCB protein function with a negative predictive value of 80%. Experimental studies have shown that this missense change affects SGCB function (PMID: 22095924). For these reasons, this variant has been classified as Pathogenic.
