Labcorp Genetics (formerly Invitae), Labcorp RCV003028590 SCV003319994 uncertain significance Autosomal recessive limb-girdle muscular dystrophy type 2K; Muscular dystrophy-dystroglycanopathy (congenital with intellectual disability), type B1; Walker-Warburg congenital muscular dystrophy 2023-08-30 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 POMT1 protein function. ClinVar contains an entry for this variant (Variation ID: 2102339). This variant has not been reported in the literature in individuals affected with POMT1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces phenylalanine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 546 of the POMT1 protein (p.Phe546Ile).
