RCV003460766 | SCV004190222 | pathogenic | RPE65-related recessive retinopathy | 2023-12-22 | reviewed by expert panel | curation | The NM_000329.3(RPE65):c.11+5G>A variant is a putative splicing variant in intron 1 of the RPE65 gene. The computational splicing predictor SpliceAI lists a change score of 0.58 for splice donor gain, predicting a deleterious impact on splicing (PP3). VCEP-member provided data from a mini-gene assay in HEK-293 cells show that this variant reduces normal splicing and leads to >400x reduction of mature mRNA, relative to the wild-type control (PS3_Supporting, Guan et al., 2024). At least 3 patients with this variant have been reported with detailed phenotypes (PMID: 21211845, PMID: 11786058), one of whom exhibited nonrecordable ERG responses from rods (0.5 pts) and cones (1 pt), congenital night blindness (0.5 pts), absence of autofluorescence (2 pts), optic nerve pallor (0.5 pts), RPE granularity (0.5 pts), onset between birth and age 5 years (1 pt), OCT preserved at macula (1 pt), constricted Goldmann visual field (1 pt), decreased central visual acuity (1 pt), and nystagmus (1 pt), which together are highly specific for recessive RPE65 retinopathy (10 pts total, VCEP member-provided data, PP4_Moderate). This variant has been detected in at least 7 published cases with recessive retinopathy, including at least two individuals homozygous for the variant (1 pt) and three individuals compound heterozygous for this variant in trans with either the c.615_616del (p.Ile206Cysfs*27), p.Glu102Ter, or c.89dup (p.Thr31fs) variant, all which have been classified Pathogenic by this VCEP (4pts, PMID: 11095629, PMID: 17525851, PMID: 35129589), (PM3_Very-Strong). Two publications contain segregation data (PMID: 11786058 and PMID: 35001204), with one set of genotype-positive siblings exhibiting the required phenotype of absent or severely decreased rod electroretinogram response (PP1). The GrpMax Filtering AF for this variant in gnomAD v2.1.1 is 0.0001017 (PM2_Supporting). In summary, this variant meets the criteria to be classified as pathogenic for RPE65-related recessive retinopathy based on the ACMG/AMP criteria applied, as specified by the ClinGen LCA/eoRD VCEP: PM3_Very-Strong, PP4_Moderate, PP1, PM2_Supporting, PP3, PS3_Supporting. (VCEP specifications version 1.0.0; date of approval 09/21/2023). |

It does not directly change the encoded amino acid sequence of the RPE65 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs61751276, gnomAD 0.02%). This variant has been observed in individual(s) with retinitis pigmentosa or Leber congenital amaurosis (PMID: 9326941, 11462243, 11786058, 19854499, 20683928, 21211845, 25257057). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is also known as 65+5G>A and IVS1+5G>A. ClinVar contains an entry for this variant (Variation ID: 98825). 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. For these reasons, this variant has been classified as Pathogenic. |

Through a review of available evidence we were able to apply the following criteria: PVS1, PM2, PM3, PP1-S, PP3, PM1. Based on this evidence we have classified this variant as Pathogenic. |

RCV001275342 | SCV002572262 | pathogenic | Leber congenital amaurosis | 2022-08-23 | criteria provided, single submitter | clinical testing | Variant summary: RPE65 c.11+5G>A alters a conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. Several computational tools predict a significant impact on normal splicing: Two predict the variant abolishes the canonical 5' splicing donor site. Two predict the variant weakens the canonical 5' splicing donor site. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 7.6e-05 in 251324 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in RPE65 causing Leber Congenital Amaurosis (7.6e-05 vs 0.0014), allowing no conclusion about variant significance. c.11+5G>A has been reported in the literature in multiple individuals affected with Leber Congenital Amaurosis/Visual impairment/Retinopathies (example, Galvin_2005, Astuti_2016, Haer-Wigman_2017, Testa_2022). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Twelve clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. |
