Invitae RCV001060884 SCV001225601 uncertain significance Mucopolysaccharidosis, MPS-III-C; Retinitis pigmentosa 73 2022-09-27 criteria provided, single submitter clinical testing This sequence change replaces leucine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 49 of the HGSNAT protein (p.Leu49Met). This variant is present in population databases (rs372961495, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with HGSNAT-related conditions. ClinVar contains an entry for this variant (Variation ID: 855589). 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 HGSNAT 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.
