Invitae | RCV001384301 | SCV001583753 | pathogenic | not provided | 2022-12-31 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. 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 disruptive. ClinVar contains an entry for this variant (Variation ID: 1071762). This missense change has been observed in individual(s) with Usher syndrome (PMID: 28559085). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 4494 of the USH2A protein (p.Tyr4494Cys). |
