Thank you for your questions. First of all, you asked me what could be the prevalence of genetic deafness. In the introduction of the article, we indicate a general prevalence of hearing loss in 2 children out of 1,000 children. Half of them are estimated to have a genetic form of hearing loss, but obviously, these data can fluctuate depending on the geographic area. Moreover, we suggest to perform genetic tests only in those patients who have clinical signs of genetic syndromes or in deaf patients with no apparent infections or any other environmental causes.
