Phenotypic Characterization of Hereditary Hearing Impairment Linked to DFNA25

Abstract

It is difficult to differentiate delayed-onset high-frequency sensorineural hearing loss inherited as a simple mendelian trait like DFNA25-associated hearing loss from that due to noise exposure or presbycusis, disorders that may also have a genetic component. An awareness of the clinical presentation of such hearing loss may help clinicians identify hearing loss attributable to genetic causes and improve care for these patients.
