About this trial
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.

Treatment groups
Trial outcomes
Primary outcomes
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.
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.
Secondary outcomes
Normative values for audiological and vestibular tests will be determined
Measurement of values by age range for all audiological and vestibular tests from the results of participants in the control group
Whole-exome sequencing of samples from participants with non-monogenic presbycusis
Whole-exome sequencing will be performed to establish a list of new candidate genes for predisposition to presbycusis.
