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]

The EYS c.6528C>A 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. Based on this evidence we have classified this variant as Likely Pathogenic. -

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The Tyr2176X variant in EYS has not been previously reported in individuals with retinitis pigmentosa or in large population studies. This nonsense variant leads to a premature termination codon at position 2176, which is predicted to lead to a truncated or absent protein. Complete loss of EYS function is an established disease mechanism in individuals with autosomal recessive retinitis pigmentosa. In summary, this variant meets our criteria to be classified as pathogenic (http://pcpgm.partners.org/LMM). -

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change creates a premature translational stop signal (p.Tyr2176*) 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 (rs797045089, gnomAD 0.003%). This premature translational stop signal has been observed in individual(s) with retinitis pigmentosa (PMID: 28704921). ClinVar contains an entry for this variant (Variation ID: 208578). For these reasons, this variant has been classified as Pathogenic. -
