Labcorp Genetics (formerly Invitae), Labcorp RCV000800436 SCV000940151 uncertain significance Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A2; Muscular dystrophy-dystroglycanopathy (congenital with intellectual disability), type B2; Autosomal recessive limb-girdle muscular dystrophy type 2N 2022-09-27 criteria provided, single submitter clinical testing This sequence change replaces methionine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 619 of the POMT2 protein (p.Met619Ile). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with POMT2-related conditions. ClinVar contains an entry for this variant (Variation ID: 646201). 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 POMT2 protein function. 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.
