Labcorp Genetics (formerly Invitae), Labcorp RCV001360645 SCV001556572 pathogenic Autosomal recessive limb-girdle muscular dystrophy type 2D 2023-08-21 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. 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 expected to disrupt SGCA protein function. ClinVar contains an entry for this variant (Variation ID: 1052453). This missense change has been observed in individual(s) with clinical features of SGCA-related conditions (PMID: 7663524; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 68 of the SGCA protein (p.Gly68Glu).
