Invitae | RCV001305273 | SCV001494602 | uncertain significance | not provided | 2022-05-27 | criteria provided, single submitter | clinical testing | This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 28 of the USH2A protein (p.Ile28Val). This variant is present in population databases (rs753515909, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with USH2A-related conditions. ClinVar contains an entry for this variant (Variation ID: 1008002). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. |

In the absence of RNA/functional studies, the actual effect of this sequence change is unknown.; In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function |
