Invitae | RCV001367272 | SCV001563617 | uncertain significance | Usher syndrome type 3B | 2020-06-17 | criteria provided, single submitter | clinical testing | This sequence change replaces isoleucine with valine at codon 498 of the HARS protein (p.Ile498Val). The isoleucine residue is moderately conserved and there is a small physicochemical difference between isoleucine and valine. This variant is not present in population databases (ExAC no frequency). 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with HARS-related conditions. |
