Genes affected
EYS (HGNC:21555): (eyes shut homolog) The product of this gene contains multiple epidermal growth factor (EGF)-like and LamG domains. The protein is expressed in the photoreceptor layer of the retina, and the gene is mutated in autosomal recessive retinitis pigmentosa. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2008]

This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 1631 of the EYS protein (p.Pro1631Ser). This variant is present in population databases (rs200935518, gnomAD 0.2%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individual(s) with retinal disease (PMID: 23591405, 25366773). ClinVar contains an entry for this variant (Variation ID: 554129). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The serine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Variant summary: EYS c.4891C>T (p.Pro1631Ser) results in a non-conservative amino acid change in the encoded protein sequence. Three of four in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00084 in 153362 control chromosomes (gnomAD). This frequency is not significantly higher than estimated for a pathogenic variant in EYS causing Retinitis Pigmentosa (0.00084 vs 0.0034), allowing no conclusion about variant significance. c.4891C>T has been reported in the literature in individuals affected with Retinitis Pigmentosa (Neveling_2012, Glckle_2013, Messchaert_2018, Colombo_2021, Karali_2022). These data do not allow any conclusion about variant significance. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 33576794, 23591405, 36460718, 29159838, 22334370). Six submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. All submitters classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -

Illumina Laboratory Services, Illumina
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
