Outline of Final Research Achievements

Clinical phenotypic information was examined retrospectively for four patients with 3q29 deletions identified using the array CGH method. All patients had treatment-resistant features, and clozapine, a treatment for treatment-resistant schizophrenia, was used in two patients and was effective in both cases.
The resting-state functional MRI analysis revealed the aberrant functional connectivity between the thalamus and visual cortex is related to attentional impairment in schizophrenia.

Academic Significance and Societal Importance of the Research Achievements

本研究は、3q29欠失を持つ統合失調症患者を対象とした神経生物学的研究によって治療抵抗性統合失調症のメカニズム解明と治療薬開発に繋がる可能性を示した。一方、統合失調症における機能的脳内ネットワークの障害と注意障害との関係を明らかにした。今後3q29欠失を持つ統合失調症患者を対象に解析を行うことで3q29欠失が脳内ネットワークおよび認知機能に与える影響を検討することができる。
