Variant summary

Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PVS1 PM2 PP5

The NM_001142800.2(EYS):​c.6545del​(p.Asn2182ThrfsTer3) variant causes a frameshift change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Likely pathogenic (no stars). Variant results in nonsense mediated mRNA decay.

• Frequency: Genomes: not found (cov: 32)
• Consequence: EYS NM_001142800.2 frameshift
• Clinical Significance: Likely pathogenic no assertion criteria provided P:2
• Conservation: PhyloP100: -0.0190

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 11 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 6-64081881-GT-G is Pathogenic according to our data. Variant chr6-64081881-GT-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 438206.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr6-64081881-GT-G is described in Lovd as [Pathogenic]. Variant chr6-64081881-GT-G is described in Lovd as [Likely_pathogenic].
