Invitae | RCV000542372 | SCV000644185 | pathogenic | Leber congenital amaurosis 2; Retinitis pigmentosa 20 | 2019-11-08 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine with glutamic acid at codon 140 of the RPE65 protein (p.Gly140Glu). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and glutamic acid. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individuals affected with Leber congenital amaurosis or retinitis pigmentosa (PMID: 28181551, 30870047). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 467827). 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: "Probably Damaging"; Align-GVGD: "Class C0"). For these reasons, this variant has been classified as Pathogenic. |
