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: Likely pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.6976C>T (p.Arg2326*) is a novel nonsense variant in the EYS gene that leads to premature truncation of the protein, causing a disorder where loss of function is a mechanism of disease. Other pathogenic nonsense variants have been described in the EYS gene in several affected individuals, linked to the disease, and reported to be in the same region as this nonsense variant (Littinik et al., 2010 and Iwanami et al., 2012). This p.Arg2326* has not been reported in the three control population databases (Exome Sequencing Project [ESP], 1000 Genomes, and ExAc) and displayed a high CADD score (45). Therefore, this collective evidence supports the classification of the c.6976C>T (p.Arg2326*) as a recessive likely pathogenic variant for Retinitis Pigmentosa-25. -

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: curation

The p.Arg2326Ter 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. -

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change creates a premature translational stop signal (p.Arg2326*) in the EYS gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in EYS are known to be pathogenic (PMID: 18836446, 20333770). This variant is present in population databases (no rsID available, gnomAD 0.008%). This premature translational stop signal has been observed in individual(s) with autosomal recessive retinitis pigmentosa (PMID: 26161267). ClinVar contains an entry for this variant (Variation ID: 402227). For these reasons, this variant has been classified as Pathogenic. -
