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]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 6-65495231-C-CA is Pathogenic according to our data. Variant chr6-65495231-C-CA is described in ClinVar as [Pathogenic]. Clinvar id is 2040666.Status of the report is criteria_provided_single_submitter, 1 stars.

Collection Method: clinical testing

This variant has not been reported in the literature in individuals affected with EYS-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Leu60Phefs*6) 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). For these reasons, this variant has been classified as Pathogenic. -
