Invitae RCV003769401 SCV004580025 pathogenic Leber congenital amaurosis 2; Retinitis pigmentosa 20 2023-11-06 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 484 of the RPE65 protein (p.Gly484Val). This variant is present in population databases (rs62653015, gnomAD 0.01%). This missense change has been observed in individuals with RPE65-related conditions (PMID: 32531858, 33308271, 37704110). ClinVar contains an entry for this variant (Variation ID: 813222). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. This variant disrupts the p.Gly484 amino acid residue in RPE65. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 20811047, 29332120, 30653986; Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
