The TECTA mutations are one of the most frequent causes of autosomal dominant (AD) hearing loss and genotype-phenotype correlations are associated with mutations of TECTA in exons according to alpha-tectorin domains. In this study, we investigated the prevalence of hearing loss caused by TECTA mutations in Japanese AD hearing loss families, and confirmed genotype-phenotype correlation, as well as the intracellular localization of missense mutations in the alpha-tectorin domain. TECTA mutations were detected in 2.9% (4/139) of our Japanese AD hearing loss families, with the prevalence in moderate hearing loss being 7.7% (4/52), and all patients showed typical genotype-phenotype correlations as previously described. The present in vitro study showed differences of localization patterns between wild type and mutants, and suggested that each missense mutation may lead to a lack of assembly of secretion, and may reduce the incorporation of alpha-tectorin into the tectorial membrane.
