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]
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]

Pathogenic, criteria provided, single submitterclinical testingInvitaeJan 21, 2024This sequence change creates a premature translational stop signal (p.Tyr3135*) in the EYS gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 10 amino acid(s) of the EYS protein. This variant is present in population databases (rs137853190, gnomAD 0.005%). This premature translational stop signal has been observed in individual(s) with EYS-related conditions (PMID: 18976725, 29159838, 30337596, 31074760). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. This variant is also known as c.9468T>A;p.Y3156X. ClinVar contains an entry for this variant (Variation ID: 538). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. For these reasons, this variant has been classified as Pathogenic. -

Likely pathogenic, criteria provided, single submitterclinical testingGeneDxOct 21, 2015The Y3156X likely pathogenic variant in the EYS gene has been reported previously in the homozygous state in two unrelated families with autosomal recessive retinitis pigmentosa (Collin et al., 2008). This variant is predicted to cause loss of normal protein function through protein truncation. Furthermore, the Y3156X variant was not observed in approximately 2,200 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Therefore, we interpret Y3156X as a likely pathogenic variant -

EYS-related disorder Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesMar 01, 2024The EYS c.9405T>A variant is predicted to result in premature protein termination (p.Tyr3135*). This variant has been reported to be causative for autosomal recessive retinitis pigmentosa (Collin et al. 2008. PubMed ID: 18976725; Ezquerra-Inchausti et al. 2018. PubMed ID: 30337596; Messchaert et al. 2018. PubMed ID: 29159838). This variant is reported in 0.0050% of alleles in individuals of Latino descent in gnomAD. Nonsense variants in EYS are expected to be pathogenic. This variant is interpreted as pathogenic. -

Pathogenic, criteria provided, single submittercurationBroad Center for Mendelian Genomics, Broad Institute of MIT and HarvardApr 01, 2021The p.Tyr3135Ter 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: PVS1, PM2, PM3-P. Based on this evidence we have classified this variant as Pathogenic. If you have any questions about the classification please reach out to the Pierce Lab. -
