What is the official name of the EYA4 gene?
The official name of this gene is “eyes absent homolog 4 (Drosophila).”
EYA4 is the gene's official symbol. The EYA4 gene is also known by other names, listed below.

What is the normal function of the EYA4 gene?
The EYA4 gene provides instructions for making a protein that plays a role in regulating the activity of other genes. Based on this role, the EYA4 protein is called a transcription factor or transcription coactivator. The EYA4 gene is active in the heart, inner ear, muscles, and other tissues throughout the body.
Two regions of the EYA4 protein, called the Eya domain and the variable domain, are important for interactions with other proteins. These protein interactions help to control gene activities that appear to be important for heart function, development of the inner ear, and maintenance of normal hearing.
Does the EYA4 gene share characteristics with other genes?
The EYA4 gene belongs to a family of genes called PTP (protein tyrosine phosphatases).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
How are changes in the EYA4 gene related to health conditions?
Genetics Home Reference provides information about familial dilated cardiomyopathy, which is also associated with changes in the EYA4 gene.
Where is the EYA4 gene located?
Cytogenetic Location: 6q23
Molecular Location on chromosome 6: base pairs 133,241,356 to 133,532,119
The EYA4 gene is located on the long (q) arm of chromosome 6 at position 23.
More precisely, the EYA4 gene is located from base pair 133,241,356 to base pair 133,532,119 on chromosome 6.
