Labcorp Genetics (formerly Invitae), Labcorp RCV002039498 SCV002116404 uncertain significance Mucopolysaccharidosis, MPS-IV-B; GM1 gangliosidosis 2022-07-25 criteria provided, single submitter clinical testing 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 GLB1 protein function. ClinVar contains an entry for this variant (Variation ID: 1350099). This variant has not been reported in the literature in individuals affected with GLB1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.007%). This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 251 of the GLB1 protein (p.Ala251Thr). 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.
