简要总结
Age-related hearing loss, or presbycusis, is caused by many genetic and environmental factors. Its prevalence poses a public health challenge of early identification and effective hearing aid treatment. However, the lack of screening and of a validated audiological test battery to diagnose an individual's needs and to guide hearing aid adjustments is a major obstacle.
Furthermore, monogenic forms of hearing loss affect only one functional module of hearing. The audiological test(s) dependent on the function of this module are affected, in a progressive manner, but not the others. A previous study showed that in early onset presbycusis patients, a quarter of the subjects tested were affected by monogenic presbycusis.
The collection of audiological and vestibular tests, carried out on proven monogenic presbycusis patients and compared to that of normal hearing patients, would constitute a battery of tests allowing a precision diagnosis, then developed to all forms of presbycusis in order to study if the identification of abnormal functional modules can usefully guide the diagnosis and the early fitting.
详细描述
The AUDIOGENAGE project is a multi-center, non-invasive case-control study conducted by CERIAH (CEntre de Recherche et d'Innovation en Human Audiology) and LCA (Laboratory de correction auditive) in 700 volunteer participants identified in two groups:
- 500 Patients with age-related hearing loss of anticipated onset,
- 200 Control subjects, considered as normal hearing for their age at inclusion.
All participants will undergo 6h audiological and vestibular tests, and also neurocognitive test (self-questionnaire). These tests will be conducted over 2 to 4 visits. A 10 mL-blood sample will be collected for a genetic analysis.

结局指标
主要结局
Measurement of specificity and sensitivity of the audiological test battery in participants with early-onset presbycusis after identification of pathogenic variants by sequencing and division into subgroups.
时间窗: 2 years
specifity and sensitivity will be calculated to identify which tests or combinations of audiological and vestibular tests will be the most discriminating in characterizing each functional module of hearing from participants with monogenic forms of presbycusis of anticipated onset, each affecting a determined functional module, in comparison with an age-matched control group.
次要结局
- Normative values for audiological and vestibular tests will be determined(4 years and 6 months)
- Whole-exome sequencing of samples from participants with non-monogenic presbycusis(4 years and 6 months)
