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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The EYS c.4402G>C; p.Asp1468His variant (rs778752557) is reported in the medical literature in two individuals with retinitis pigmentosa, one of whom carried an alternative molecular explanation for disease (Ge 2015, Wang 2014). The variant is described in the ClinVar database (Variation ID: 195938) and is listed in the Genome Aggregation Database with an allele frequency of 0.2% (30/16324 alleles) in the African population. The aspartic acid at codon 1468 is moderately conserved and computational analyses (SIFT: Tolerated, PolyPhen-2: Possibly damaging) predict conflicting effects of this variant on protein structure/function. Although there is information indicating this variant may be likely benign, there is insufficient evidence to classify the variant with certainty. Pathogenic EYS variants are causative for autosomal recessive retinitis pigmentosa (MIM: 602772). References: Ge Z et al. NGS-based Molecular diagnosis of 105 eyeGENE probands with Retinitis Pigmentosa. Sci Rep. 2015 Dec 15;5:18287. Wang J et al.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces aspartic acid, which is acidic and polar, with histidine, which is basic and polar, at codon 1468 of the EYS protein (p.Asp1468His). This variant is present in population databases (rs778752557, gnomAD 0.2%). 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, 34906470). ClinVar contains an entry for this variant (Variation ID: 195938). 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. -

In silico analysis indicates that this missense variant does not alter protein structure/function; Observed with additional EYS variants, including the c.3443+1G>T pathogenic variant, in an individual with peripheral dystrophy, however, segregation data was not provided to determine whether the variants occurred on the same (in cis) or on different (in trans) chromosomes (PMID: 25097241); 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); This variant is associated with the following publications: (PMID: 36284670, 36819107, 29550188, 31736247, 39588395, 26667666, 25097241) -

The EYS c.4402G>C variant is predicted to result in the amino acid substitution p.Asp1468His. 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.3250A>C (p.Thr1084Pro) (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 0.20% 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. -

The p.Asp1468His variant in EYS was identified in an individual with Retinitis pigmentosa, via a collaborative study between the Broad Institute's Center for Mendelian Genomics and the Pierce lab (https://oculargenomics.meei.harvard.edu/labs/pierce-lab/lab-members/). Through a review of available evidence we were able to apply the following criteria: PM2, PM3-P. Based on this evidence we have classified this variant as a Variant of Uncertain Significance. If you have any questions about the classification please reach out to the Pierce Lab. -
