RCV001247134 | SCV001420541 | uncertain significance | Mucopolysaccharidosis type 6 | 2021-08-30 | criteria provided, single submitter | clinical testing | This sequence change replaces proline with alanine at codon 15 of the ARSB protein (p.Pro15Ala). The proline residue is moderately conserved and there is a small physicochemical difference between proline and alanine. While this variant is present in population databases (rs778159305), the frequency information is unreliable, as metrics indicate poor data quality at this position in the ExAC database. This variant has not been reported in the literature in individuals affected with ARSB-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0"). 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. |
