Genes affected

EYA4 (HGNC:3522): (EYA transcriptional coactivator and phosphatase 4) This gene encodes a member of the eyes absent (EYA) family of proteins. The encoded protein may act as a transcriptional activator through its protein phosphatase activity, and it may be important for eye development, and for continued function of the mature organ of Corti. Mutations in this gene are associated with postlingual, progressive, autosomal dominant hearing loss at the deafness, autosomal dominant non-syndromic sensorineural 10 locus. The encoded protein is also a putative oncogene that mediates DNA repair, apoptosis, and innate immunity following DNA damage, cellular damage, and viral attack. Defects in this gene are also associated with dilated cardiomyopathy 1J. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2014]

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. There are 15 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 6-133274793-C-T is Pathogenic according to our data. Variant chr6-133274793-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 3655361.Status of the report is criteria_provided_single_submitter, 1 stars.

This sequence change creates a premature translational stop signal (p.Gln5*) in the EYA4 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in EYA4 are known to be pathogenic (PMID: 11159937, 25781927, 25963406). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with EYA4-related conditions. For these reasons, this variant has been classified as Pathogenic. -
