RCV004527320 | SCV005038783 | likely pathogenic | RPE65-related recessive retinopathy | 2024-04-22 | reviewed by expert panel | curation | NM_000329.3(RPE65):c.859G>T (p.Val287Phe) is both a missense variant, changing the valine at position 287 to phenylalanine, and a possible splicing variant, located at the first nucleotide of exon 9. SpliceAI's highest score is for Acceptor Loss, at 0.07, predicting a non-deleterious effect on splicing. The computational predictor REVEL has a score of 0.887, which is above the ClinGen LCA / eoRD VCEP threshold of ≥ 0.774 and predicts a damaging effect on RPE65 function (PP3_moderate). This variant is absent from gnomAD v2.1.1 (PM2_Supporting). At least one proband harboring this variant exhibits a phenotype including diagnosis of LCA (0.5 pts) and significant improvement after gene therapy treatment (8 pts), which together are highly specific for RPE65-related recessive retinopathy (8.5 points, PMID: 21911650 , PP4_Moderate). This variant has been reported in at least 2 unrelated probands with early-onset severe retinal dystrophy who were homozygous for the variant (1 point, PMIDs: 18722466, 21911650). (1.0 total points, PM3). In summary, this variant meets the criteria to be classified as Likely Pathogenic for RPE65-related recessive retinopathy based on the ACMG/AMP criteria applied, as specified by the ClinGen LCA/eoRD VCEP: PP3_moderate, PM2_supporting, PP4_moderate, PM3. (VCEP specifications version 1.0.0; date of approval 09/21/2023). |
