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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.Asp301Asn variant in EYA4 has not been previously reported in individuals with hearing loss, but has been identified in 5/126018 European chromosomes by t he Genome Aggregation Database (gnomAD, http://gnomAD.broadinstitute.org; dbSNP rs779172192). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational predi ction tools and conservation analysis do not provide strong support for or again st an impact to the protein. In summary, the clinical significance of the p.Asp3 01Asn variant is uncertain. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

ClinVar contains an entry for this variant (Variation ID: 517314). This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 301 of the EYA4 protein (p.Asp301Asn). This variant is present in population databases (rs779172192, gnomAD 0.005%). This variant has not been reported in the literature in individuals affected with EYA4-related conditions. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt EYA4 protein function. 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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.D301N variant (also known as c.901G>A), located in coding exon 10 of the EYA4 gene, results from a G to A substitution at nucleotide position 901. The aspartic acid at codon 301 is replaced by asparagine, 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 tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
