Genetic Testing for Hearing Loss

The American Society of Human Genetics recognizes that genetic testing is an integral part of the evaluation of a child with nonsyndromic hearing loss and has developed specific guidelines for incorporating genetic testing into your clinical practice [Genet Med 2002:4(3) 162-171].

Genetic test results may provide:

• Accurate determination of the etiology of the patient's hearing loss
• Reduction or elimination of the need for further invasive and costly diagnostic tests
• Basis for prognostic information about future hearing and potential medical complications
• Guidance regarding treatment and long-term medical management, particularly in the young infant
• Definitive information on which to base genetic counseling of families

Most insurance companies cover genetic testing of patients with hearing loss. Genetic testing early in the evaluation process may actually reduce costs related to the diagnostic evaluation [Otology and Neurology (2005) 26:610-615].
