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 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. -

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) -

Variant summary: EYS c.1852G>A (p.Gly618Ser) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00016 in 188434 control chromosomes (gnomAD). This frequency is not significantly higher than expected for a pathogenic variant in EYS causing Retinitis Pigmentosa (0.00016 vs 0.0034), allowing no conclusion about variant significance. c.1852G>A has been reported in the literature in individuals affected with Retinitis Pigmentosa (Gonzalez-del Pozo_2011, Sharon_2020), including one confirmed compound heterozygote (Audo_2010). 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. Four ClinVar submitters have assessed the variant since 2014: three classified the variant as of uncertain significance and one as likely pathogenic. Based on the evidence outlined above, the variant was classified as uncertain significance. -
