Labcorp Genetics (formerly Invitae), Labcorp RCV001062845 SCV001227668 pathogenic Autosomal recessive limb-girdle muscular dystrophy type 2D 2022-08-16 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 857216). This missense change has been observed in individual(s) with clinical features of limb-girdle muscular dystrophy (Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces leucine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 302 of the SGCA protein (p.Leu302Arg).
