Brief summary

This registry is designed to collect comprehensive information about the molecular genetic diagnoses and clinical information of individuals with CABP2-associated hearing impairment to support a natural history study.

Detailed description

A patient registry, in both German and English languages, has been established for patients with hereditary hearing impairment due to variants in CABP2. The study is conducted in accordance with the current version of the Declaration of Helsinki. The study protocol and database structure have been approved by the Ethics Committee of the University Medical Center Goettingen.

Interventions

Genetic testing and audiometry are the interventions of interest

Design outcomes

Primary

MeasureTime frameDescription
Pure-tone audiometry1 year, year 1, according to participant consentPure tone audiometry is a behavioral hearing test used to measure an individual's hearing threshold levels
Speech audiometry1 year, year 1, according to participant consentSpeech audiometry is a test or series of tests to determine a patient's ability to discriminate speech sounds and hearing speech or speech in noise

Secondary

MeasureTime frameDescription
Otoacoustic emission thresholds1 year, year 1, according to participant consentOtoacoustic emission thresholds serve as indicators of integrity and function of the outer hair cells in the cochlea
Auditory brainstem response1 year, year 1, according to participant consentAuditory brainstem response tests the functional status of the auditory neural pathway
