Genetics of hearing loss

The Cochlear Implant Program at The Hospital for Sick Children has been involved in exciting new research into the genetic background of hearing loss.  We have already tested over 300 children with cochlear implants and over 1000 of their family members.  We would like to thank you for taking the time to read over the following information and for helping to advance our knowledge of hearing loss.
