Detailed Description
The aim of the study is to evaluate the diagnostic value of a new panel of gene in NGS study in children presenting :
- A congenitally deafness : it is a retrospective study in children aged 0 to 17 yrs with hearing thresholds over 40 dB in the best ear using adapted audiometric assessment,
- A suspicion of deafness in babies aged 0 to 6 months having an abnormal response after otoacoustic emissions and automated ABR assessment.
The main outcomes studied will be the finding of a pathogenic mutation (or several mutations).
