Retrospective Analysis of the Outcomes of Genetic Testing in Patients Suspected to Have Hereditary Hearing Loss or Deafness.

Our study suggests a significant association between sensorineural type of hearing loss and a diagnostic positive genetic test result, while the presence of disabilities was significantly associated with a nondiagnostic genetic test result. Knowledge of these findings is critical for understanding the cause of the hearing loss, identifying other associated symptoms, and determining risk to family members.
