NM_000329.3(RPE65):c.1292A>G is a missense variant predicted to cause substitution of tyrosine by cysteine at amino acid 431. This variant is present in gnomAD v.2.1.1 at a GrpMax allele frequency of 0.00002, with 1/113326 total alleles in the European (Non-Finnish) population, which is lower than the ClinGen LCA / eoRD VCEP PM2_Supporting threshold of <0.0002 (PM2_Supporting). This variant has been reported in at least 2 probands with early-onset severe retinal dystrophy who were compound heterozygous with either the c.907A>T (p.Lys303Ter) or c.1102T>C (p.Tyr368His) variants confirmed in trans (2 point, PMIDs: 14962443, 30268864), which were previously classified pathogenic by the ClinGen LCA / eoRD VCEP (2 total points, PM3_Strong). At least one proband harboring this variant exhibits a phenotype including clinical diagnosis of Leber congenital amaurosis (0.5 pts), absent or severely decreased rod electroretinogram responses (0.5 pts), congenital night blindness (0.5 pts), optic nerve pallor (0.5 pts), Pigmentary retinopathy with attenuated vessels (0.5 pts), macular atrophy (0.5 pts), symptomatic onset between birth and age five years (1 pt), decreased central visual acuity (1 pt), abnormal color vision or evidence of cone involvement on ERG (1 pt), nystagmus (1 pt), and significant improvement following gene therapy (8 pt) which together are highly specific for RPE65-related recessive retinopathy (PMIDs: 14962443, 19117922, 22323828, 15 points, PP4_Moderate). The computational predictor REVEL gives a score of 0.94, which is above the ClinGen LCA / eoRD VCEP threshold of ≥ 0.773 and predicts a damaging effect on RPE65 function (PP3_Moderate). 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/eoRP VCEP: PM3_Strong, PP4_Moderate, PM2_Supporting, and PP3_Moderate.
