NM_000329.3(RPE65):c.1244-5C>T is a non-coding variant in intron 11 near the junction with exon 12. This variant is present in gnomAD v.2.1.1 at a GrpMax allele frequency of 0.002561, with 70 alleles / 24966 total alleles in the African/African-American population, which is higher than the ClinGen LCA / eoRD VCEP BS1 threshold of >0.0008 (BS1). The splicing impact predictor SpliceAI gives scores of 0.26 for acceptor gain and 0.20 for donor gain, which are above the ClinGen LCA / eoRD VCEP recommended threshold of ≥0.2 and predict a damaging impact on splicing (PP3). In summary, this variant meets the criteria to be classified as likely benign for RPE65-related recessive retinopathy based on the ACMG/AMP criteria applied, as specified by the ClinGen LCA / eoRD VCEP: BS1 and PP3 (VCEP specifications version 1.0.0; date of approval 09/21/2023).

Met criteria codes

• PP3: The splicing impact predictor SpliceAI gives scores of 0.26 for acceptor gain and 0.20 for donor gain, which are above the ClinGen LCA / eoRD VCEP recommended threshold of ≥0.2 and predict a damaging impact on splicing (PP3).
• BS1: This variant is present in gnomAD v.2.1.1 at a GrpMax allele frequency of 0.002561, with 70 alleles / 24966 total alleles in the African/African-American population, which is higher than the ClinGen LCA / eoRD VCEP BS1 threshold of >0.0008 (BS1).
