RCV001850105 | SCV002109881 | uncertain significance | Autosomal recessive limb-girdle muscular dystrophy type 2O; Muscular dystrophy-dystroglycanopathy (congenital with intellectual disability), type B3 | 2022-07-11 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 488 of the POMGNT1 protein (p.Arg488Gly). This variant is present in population databases (rs727504103, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with POMGNT1-related conditions. ClinVar contains an entry for this variant (Variation ID: 167527). 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 expected to disrupt POMGNT1 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. |
