Labcorp Genetics (formerly Invitae), Labcorp RCV002020128 SCV002289921 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 2022-12-02 criteria provided, single submitter clinical testing 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. 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on POMT2 protein function. ClinVar contains an entry for this variant (Variation ID: 1502221). This variant has not been reported in the literature in individuals affected with POMT2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces asparagine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 523 of the POMT2 protein (p.Asn523Ile).
