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]

Variant summary: EYS c.2886C>G (p.Phe962Leu) results in a non-conservative amino acid change located in the EGF-like domain (IPR000742) of the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. c.2886C>G has been reported in the literature as co-occurring with EYS c.2892A>C (p.Glu964Asp) in all instances ascertained among individuals affected with features of Leber congenital amaurosis (LCA) (example, Eisenberger_2013) or Retinitis Pigmentosa (example, Koyanagi_2019, Numa_2020, Gao_2022). In at-least two of these ascertainments, this variant combination also occurred along with a third EYS allele, again without phase specifications, among individuals affected with Retinitis Pigmentosa (n=2, c.8868delT (p.Ala2957fs), Koyanagi_2019 and n=1, c.2582G>A (p.Gly843Asp), Numa_2020). Furthermore, this variant combination also occurred without phase specifications, and therefore as a non-informative genotype alongside a majority concordant benign/likely benign EYS variant c.5510G>C (p.Trp1837Ser) in an individual with LCA (Eisenberger_2013). These report(s) do not provide unequivocal conclusions about association of the variant with Retinitis Pigmentosa or Leber congenital amaurosis. Both these variant alleles are found at a frequency of 5.2e-05 in 153916 and 154094 control chromosomes respectively in gnomAD (v2) database, further supporting a co-occuring haplotype. The available data on variant occurrences in the general population are insufficient to 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: 24265693, 34689181, 31213501, 33247286). Two 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 in isolation was classified as uncertain significance. -

This sequence change replaces phenylalanine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 962 of the EYS protein (p.Phe962Leu). This variant is present in population databases (rs766153322, gnomAD 0.06%). This missense change has been observed in individual(s) with EYS-related conditions (PMID: 24265693, 33247286). ClinVar contains an entry for this variant (Variation ID: 554347). 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 leucine 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. -
