Outline of Final Research Achievements

Somatic mutations occur in genomic DNA in the cranial nervous system contribute to the diversity of structures and functions of neural cells. In addition, their frequency and patterns are considered to be deeply related to the pathophysiology of psychiatric disorders. In this project, we established techniques detecting somatic mutation detection and applied them to analysis of postmortem brain of schizophrenia patients. As a result, we established new pipelines to extract somatic mutations from genomic information and identified somatic mutations in the brain samples of schizophrenia patients.

Academic Significance and Societal Importance of the Research Achievements

本研究で確立した体細胞変異検出のためのバイオインフォマティクスパイプラインは、今後、精神疾患の様々なゲノム解析データに適用可能であり、精神疾患の病因・病態の理解が進むと期待される。また、本解析手法を応用することにより、分化・発生・老化や他の疾患研究に広く適用可能である。
