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]

Reported in the homozygous state in patients with retinitis pigmentosa in published literature, however, these individuals were also homozygous for the c.3443+1G>T pathogenic variant in the EYS gene (PMID: 26667666, 29550188); In silico analysis indicates that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 36819107, 31736247, 39588395, 25097241, 29550188, 26667666) -

This sequence change replaces threonine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 1084 of the EYS protein (p.Thr1084Pro). This variant is present in population databases (rs778646190, gnomAD 0.1%). This missense change has been observed in individual(s) with retinal disease. However, this variant has frequently been identified on the same chromosome as other EYS variants, making its clinical significance uncertain (PMID: 25097241, 26667666, 29550188). ClinVar contains an entry for this variant (Variation ID: 195666). 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 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. -

The EYS c.3250A>C variant is predicted to result in the amino acid substitution p.Thr1084Pro. This variant has been reported in individuals with retinitis pigmentosa; however, in several of these cases it was determined to be on the same allele (in cis) with the pathogenic variant c.3443+1G>T as well as the uncertain missense variant c.4402G>C (p.Asp1468His) (Wang et al. 2014. PubMed ID: 25097241; Ge et al. 2015. PubMed ID: 26667666; Sengillo et al. 2018. PubMed ID: 29550188). This variant is reported in 0.15% of alleles in individuals of African descent in gnomAD. Although we suspect that this variant may be benign by itself, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
