Novel Genetic Loci Identified for High Frequency Hearing Loss

The genetics responsible for frequency-specific hearing loss have
remained elusive until recently, when genetic loci were found that
affected high-frequency hearing. Now, a study reports, for the first
time, genetic loci with effects that are limited to specific portions of
the hearing frequency map.
