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:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Frameshift: predicted to result in a loss or disruption of normal protein function through nonsense-mediated decay (NMD) or protein truncation. Multiple pathogenic variants are reported downstream of the variant (PVS1_VS). It is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.000275, PM2_M). The variant has been reported at least twice as pathogenic/likely pathogenic with clinical assertions and evidence for the classification (ClinVar ID: VCV000281325, PMID:20333770). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Pro2265Glnfs*46) 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 (rs758109813, gnomAD 0.3%). This premature translational stop signal has been observed in individual(s) with retinitis pigmentosa (PMID: 25412400, 29550188). ClinVar contains an entry for this variant (Variation ID: 281325). For these reasons, this variant has been classified as Pathogenic. -

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: EYS c.6794delC (p.Pro2265GlnfsX46) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. The variant allele was found at a frequency of 0.00018 in 157910 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in EYS causing Retinitis Pigmentosa (0.00018 vs 0.0034), allowing no conclusion about variant significance. c.6794delC has been reported in the literature in individuals affected with Retinitis Pigmentosa (e.g. Consugar_2015). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. ClinVar contains an entry for this variant (Variation ID: 281325). Based on the evidence outlined above, the variant was classified as pathogenic. -

Significance:Pathogenic

Review Status:no assertion criteria provided

Collection Method:clinical testing

The EYS c.6794delC variant is predicted to result in a frameshift and premature protein termination (p.Pro2265Glnfs*46). This variant has been reported in multiple individuals with retinitis pigmentosa (Audo et al. 2010. PubMed ID: 20333770; Supplementary Table, Zanolli et al. 2020. PubMed ID: 32141364; Georgiou et al. 2020. PubMed ID: 32795431). This variant is reported in 0.29% of alleles in individuals of African descent in gnomAD, indicating it is relatively common. Frameshift variants in EYS are expected to be pathogenic. Given the evidence, we interpret this variant as pathogenic. -
