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]

Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

Variant classified as Uncertain Significance - Favor Benign. The c.723A>G (p.Pro 241Pro) variant in EYA4 has not been previously reported in individuals with hea ring loss and was absent from large population studies. This variant is located in the last two bases of the exon, which is part of the 3? splice region. Comput ational tools do not predict altered splicing, and four species (rhesus, crab-ea ting macaque, baboon, green monkey) have guanine (G) at this nucleotide position . However, this information is not predictive enough to rule out pathogenicity. In summary, while the clinical significance of the c.723A>G variant is uncertai n, the computational and conservation data suggests it is more likely to be beni gn. -

Dilated cardiomyopathy 1J Uncertain:1
Mar 11, 2024
Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change affects codon 241 of the EYA4 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the EYA4 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs556550485, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with EYA4-related conditions. ClinVar contains an entry for this variant (Variation ID: 228682). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. 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:Likely benign

Cardiovascular phenotype Benign:1
Jan 28, 2020
Ambry Genetics
Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
