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]

Pathogenic, no assertion criteria provided	clinical testing	Natera, Inc.	Jul 08, 2020	- -
Pathogenic, criteria provided, single submitter	clinical testing	3billion	Jan 03, 2022	Stop-gained (nonsense): 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). The variant has been reported at least twice as pathogenic/likely pathogenic with clinical assertions and evidence for the classification (ClinVar ID: VCV000197186, PMID:22581970). It is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.000008, PM2_M). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline. -
Pathogenic, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Sep 22, 2021	The EYS c.490C>T (p.Arg164Ter) variant is a stop-gained variant that is predicted to result in a premature termination of the protein. The variant has been reported in a compound heterozygous state in at least five individuals, including two siblings, affected with retinitis pigmentosa (O'Sullivan et al. 2012; Chen et al. 2015; McGuigan et al. 2017). The variant is reported at a frequency of 0.000008 in the Total population of the Genome Aggregation database (version 2.1.1), though this is based on only two occurrences in a region of good sequence coverage, so the variant is presumed to be rare. Based on the collective evidence, the p.Arg164Ter variant is classified as pathogenic for autosomal recessive retinitis pigmentosa. -

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Dec 22, 2023	This sequence change creates a premature translational stop signal (p.Arg164*) 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 (rs794727631, gnomAD 0.003%). This premature translational stop signal has been observed in individuals with retinitis pigmentosa (PMID: 22581970, 25753737). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 197186). For these reasons, this variant has been classified as Pathogenic. -
