Labcorp Genetics (formerly Invitae), Labcorp RCV001994276 SCV002270571 uncertain significance Autosomal recessive limb-girdle muscular dystrophy type 2F 2021-04-23 criteria provided, single submitter clinical testing This sequence change replaces methionine with valine at codon 217 of the SGCD protein (p.Met217Val). The methionine residue is weakly conserved and there is a small physicochemical difference between methionine and valine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with SGCD-related conditions. 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, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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.
