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]

The EYA4 c.1109G>A variant is predicted to result in the amino acid substitution p.Arg370His. This variant was reported in an individual with hearing loss, although further evidence of pathogenicity was not presented (Truong et al. 2019. PubMed ID: 30828794). This variant is reported in 0.0065% of alleles in individuals of South Asian descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 370 of the EYA4 protein (p.Arg370His). This variant is present in population databases (rs143936434, gnomAD 0.007%). This missense change has been observed in individual(s) with hearing loss (PMID: 30828794). ClinVar contains an entry for this variant (Variation ID: 163451). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

The p.R370H variant (also known as c.1109G>A), located in coding exon 12 of the EYA4 gene, results from a G to A substitution at nucleotide position 1109. The arginine at codon 370 is replaced by histidine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
