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]

In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; Identified in individuals with retinitis pigmentosa in published literature, however, this variant did not segregate with disease in one family and another study considered this variant to be likely benign (Audo et al., 2010; Gonzalez-del Pozo et al., 2011; Messchaert et al., 2018); This variant is associated with the following publications: (PMID: 22164218, 29159838, 20333770, 31456290)

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 618 of the EYS protein (p.Gly618Ser). This variant is present in population databases (rs142450703, gnomAD 0.1%). This missense change has been observed in individuals with clinical features of EYS-related conditions (PMID: 20333770, 31456290, 35836572; internal data). ClinVar contains an entry for this variant (Variation ID: 551873). 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%. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.

Variant summary: EYS c.1852G>A (p.Gly618Ser) results in a non-conservative amino acid change in the encoded protein sequence. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change. The variant allele was found at a frequency of 0.00011 in 157080 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in EYS causing Retinitis Pigmentosa (0.00011 vs 0.0034), allowing no conclusion about variant significance. c.1852G>A has been observed in individuals affected with Retinitis Pigmentosa (e.g., Audo_2010, Gonzalez-delPozo_2011, Maltese_2022, Placidi_2023, Sharon_2020, internal data). These data indicate that the variant is likely to be associated with disease. 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: 20333770, 22164218, 35836572, 36899994, 31456290). ClinVar contains an entry for this variant (Variation ID: 551873). Based on the evidence outlined above, the variant was classified as likely pathogenic.
