USH TALKS: GENE THERAPY FOR USHER SYNDROME TYPE 1C

February 06, 2017

Gwenaëlle Géléoc, PhD

In this USH Talk, Dr. Gwen Géléoc shares exciting news on progress made towards gene therapy for Usher syndrome type 1c. Working with a mouse model of a human mutation, Dr. Géléoc and colleagues delivered a normal copy of the Ush1c gene to the inner ear soon after the mice were born. This led to robust improvements enabling profoundly deaf and dizzy mice to hear sounds at the level of whispers and recover proper balance function. Dr. Géléoc is cautiously optimistic that successes in the lab will someday lead to novel therapeutic approaches in the clinic.

Gene therapy restores hearing in deaf mice

Vector Blog, Boston Children's Hospital 

More than 70 different genes are known to cause deafness when mutated. Jeffrey Holt, PhD, envisions a day when patients with hearing loss have their genome sequenced and their hearing restored by gene therapy. A proof-of-principle study published today by the journal Science Translational Medicinetakes a clear step in that direction, restoring hearing in deaf mice.

How things work: Scientists find cellular channels vital for hearing

July 31, 2013

Vector Blog –Boston Children’s Hospital

Each sensory cell, of which the human ear has about 16,000, has tiny hairs tipped with TMC1 and TMC2 proteins. When sound vibrations strike the bundle, it wiggles back and forth, opening and closing the TMC channels. When open, the channel allows calcium into the cell, initiating an electrical signal to the brain relayed by the 8th cranial nerve.
