Outline of Final Research Achievements |
In this program, we conducted a comprehensive analysis of association between alternative splicing and neuropsychiatric disorders. Specifically, we reported the results of genome-wide identification of splicing quantitative trait loci (sQTLs) in the human brain and analysis of their association with neuropsychiatric disorders such as schizophrenia (Takata et al., Nature Communications 2017), and large-scale exome studies of autism spectrum disorder and developmental and epileptic encephalopathy analyzing rare variants including those potentially affect alternative splicing (Takata et al., Cell Reports 2018, Takata et al., Nature Communications 2019).

Academic Significance and Societal Importance of the Research Achievements |
本研究で作製した、選択的スプライシングに影響を及ぼす変異の網羅的カタログは、ゲノムワイド関連解析等で検出される疾患関連SNPの生物学的意義の解釈と、疾患メカニズム解明に活用することができる。また、エクソーム解析等の網羅的ゲノム解析において、選択的スプライシング影響する変異を考慮することで、遺伝子診断につながる病的変異や、疾患リスクに寄与する変異を同定できる確率の向上が見込める。これらはいずれも、精神神経疾患のゲノム・脳病態理解と、診断・予防・将来の治療法開発に貢献しうるものである。
