| Outline of Final Research Achievements |
Auditory Neuropathy (AN) is a new concept of hearing loss with the clinical feature of poor recognition of words. The purpose of this study is to reveal novel genetic causes of AN. By Sanger sequencing analysis in 36 patients with AN, we detected 11 novel OTOF mutations in 25 patients and 1 known GJB2 mutation in a patient. By whole genome SNP analysis followed by real time PCR analysis in 4 patients with monoallelic OTOF mutations, we did not detect large deletions in OTOF. With exome analysis in 10 patients who had not been found genetic causes by previous genetic analyses, we detected 3 candidates of novel AN genes (PNPLA3, RYR3, TACC2) and a novel OPA1 mutation which is likely to be a de novo mutation.
