A geneticist at Tel Aviv University discovered a defective gene that causes progressive hearing loss. Karen Avraham led an international team of researchers who found that a defect in DFNA15 caused moderate to severe deafness by age 40 in one large Israeli family.

The DFNA15 gene regulates the function of many other genes, so the ability to isolate and correct that gene could affect the function of other genes that control hearing.
