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.3695T>C (p.Ile1232Thr) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 7.7e-05 in 155446 control chromosomes (gnomAD). This frequency is not significantly higher than estimated for a pathogenic variant in EYS causing Retinitis Pigmentosa (7.7e-05 vs 0.0034), allowing no conclusion about variant significance. c.3695T>C has been reported in the literature in individuals affected with Retinitis Pigmentosa (examples: Gonzlez-del Pozo_2011, Messchaert_2018, Xu_2021). 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: 22164218, 29159838, 34178978). ClinVar contains an entry for this variant (Variation ID: 551910). Based on the evidence outlined above, the variant was classified as uncertain significance. -

Collection Method: clinical testing

This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 1232 of the EYS protein (p.Ile1232Thr). This variant is present in population databases (rs146413074, gnomAD 0.04%). This missense change has been observed in individual(s) with retinitis pigmentosa (PMID: 22164218, 29159838). ClinVar contains an entry for this variant (Variation ID: 551910). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt EYS protein function with a negative predictive value of 80%. This variant disrupts the p.Ile232 amino acid residue in EYS. Other variant(s) that disrupt this residue have been observed in individuals with EYS-related conditions (PMID: 20333770), which suggests that this may be a clinically significant amino acid residue. 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. -
