Researchers have found long-sought genes in the sensory hair cells of the inner ear that, when mutated, prevent sound waves from being converted to electric signals – a fundamental first step in hearing. The team, co-led by Jeffrey Holt, PhD, in the department of otolaryngology at Children’s Hospital Boston, and Andrew Griffith, MD, PhD, of the NIH’s National Institute on Deafness and other Communication Disorders (NIDCD), then restored these electrical signals in the sensory cells of deaf mice by introducing normal genes.
