Outline of Final Research Achievements

We developed an experimental approach to efficiently quantify the pathogenic effects of disease-associated genetic variants with a focus on SLC26A4, which is essential for normal inner ear function. Alterations of this gene are associated with both syndromic and nonsyndromic hereditary hearing loss with various degrees of severity. We established HEK293T-based stable cell lines that express pendrin missense variants in a doxycycline-dependent manner, and systematically determined their anion transport activities with high accuracy in a 96-well plate format using a high throughput plate reader.
Based on the method, we also developed an experimental approach to quantify the function of wild-type and variant of NLCC1(SLC12A2 gene).

Academic Significance and Societal Importance of the Research Achievements

近年の遺伝子解析技術の進歩により多くの遺伝子バリアントが発見されるが、そのバリアントが難聴の原因になのかどうかの判断は非常に難しい場合がある。今回の研究で開発した解析法では効率的にバリアントの機能への影響を定量することが可能であることから、どのバリアントがどのように疾患に関わっているのかを定量化することができる基礎的データを構築することができた。
