Description

This variant is present in population databases (no rsID available, gnomAD 0.009%). For these reasons, this variant has been classified as Pathogenic. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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"). ClinVar contains an entry for this variant (Variation ID: 427864). This missense change has been observed in individual(s) with Leber congenital amaurosis (PMID: 26047050, 28714225, 30870047). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This sequence change replaces arginine, which is basic and polar, with serine, which is neutral and polar, at codon 446 of the RPE65 protein (p.Arg446Ser). This variant also falls at the last nucleotide of exon 12, which is part of the consensus splice site for this exon.
