RCV002002308 | SCV002227746 | uncertain significance | Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A13 | 2022-12-06 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 137 of the B4GAT1 protein (p.Val137Met). 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) performed at Invitae indicates that this missense variant is not expected to disrupt B4GAT1 protein function. ClinVar contains an entry for this variant (Variation ID: 1448687). This variant has not been reported in the literature in individuals affected with B4GAT1-related conditions. This variant is present in population databases (rs376914969, gnomAD 0.003%). |
