Labcorp Genetics (formerly Invitae), Labcorp RCV002848330 SCV003230937 uncertain significance Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type a, 8 2022-02-04 criteria provided, single submitter clinical testing This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 497 of the POMGNT2 protein (p.Ala497Thr). This variant is present in population databases (rs755335888, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with POMGNT2-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. 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.
