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 Benign. Variant got -13 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.71).
• BP6: Variant 6-65707146-G-A is Benign according to our data. Variant chr6-65707146-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 357760.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Benign=3, Uncertain_significance=1}.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0121 (1844/152154) while in subpopulation NFE AF= 0.0159 (1079/68000). AF 95% confidence interval is 0.0151. There are 12 homozygotes in gnomad4. There are 832 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 12 AR gene

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -
