RCV001992244 | SCV002284112 | uncertain significance | Cone-rod dystrophy 13; Leber congenital amaurosis 6 | 2021-09-01 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine with valine at codon 228 of the RPGRIP1 protein (p.Ala228Val). The alanine residue is weakly conserved and there is a small physicochemical difference between alanine and valine. This variant is present in population databases (rs756504836, ExAC 0.002%). This variant has not been reported in the literature in individuals affected with RPGRIP1-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: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). 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. |
