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]

EYS links:

PHF3 (HGNC:8921): (PHD finger protein 3) This gene encodes a member of a PHD finger-containing gene family. This gene may function as a transcription factor and may be involved in glioblastomas development. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2014]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The EYS c.8133_8137delCTTTC; p.Phe2712fs variant (rs751629543), also known as c.8196_8200delCTTTC p.F2733Cfs*33 based on NM_001292009.1, is published in the medical literature in a family with autosomal recessive retinitis pigmentosa (Arai 2015). The variant is listed in the ClinVar database (Variation ID: 558163) and in the general population with an allele frequency of 0.006% (9/148188 alleles) in the Genome Aggregation Database. This variant causes a frameshift by deleting 5 nucleotides so it is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Additionally, this variant is predicted to cause loss of a critical functional domain (Hosono 2012). Considering available information, this variant is predicted to be pathogenic.

The EYS c.8133_8137del variant was identified in an individual with retinitis pigmentosa with a presumed recessive inheritance pattern. Through a review of available evidence we were able to apply the following criteria: PVS1, PM2, PM3. Based on this evidence we have classified this variant as Pathogenic. -

This sequence change creates a premature translational stop signal (p.Phe2712Cysfs*33) in the EYS gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 433 amino acid(s) of the EYS protein. This variant is present in population databases (rs751629543, gnomAD 0.02%). This premature translational stop signal has been observed in individual(s) with retinitis pigmentosa (PMID: 26161267, 30153090). ClinVar contains an entry for this variant (Variation ID: 558163). This variant disrupts a region of the EYS protein in which other variant(s) (p.Thr3038Ilefs*4 and p.Asn3061Thrfs*3) have been determined to be pathogenic (PMID: 20333770, 21069908). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
