Invitae RCV001364303 SCV001560443 uncertain significance Mucopolysaccharidosis, MPS-III-C; Retinitis pigmentosa 73 2023-10-03 criteria provided, single submitter clinical testing This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 411 of the HGSNAT protein (p.Pro411Thr). This variant is not present in population databases (gnomAD no frequency). 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: 1055603). 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 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.
