Child Cochlear Implant
Genetic testing for childhood hearing loss
Genetic testing identifies a cause in roughly half of cases of unexplained childhood hearing loss. It informs family planning, prognosis and related health monitoring.
Commonly tested genes include GJB2 (connexin 26), SLC26A4 (Pendred), MYO7A and MYO15A. Single-gene tests, panels and whole-exome sequencing are increasingly accessible in India.
Genetic findings rarely change CI decisions in the short term but they provide families with answers, support genetic counselling, and identify children at risk of further hearing loss or related medical issues.
