Outline of Final Research Achievements

Rare genomic variations inherited in multiplex schizophrenia families are suggested to play a role in the genetic etiology of the disease. To identify rare variations with large effects on the risk of developing schizophrenia, we performed whole-exome sequencing(WES) in a multiplex family. We also performed follow-up resequencing of a potential risk gene identified by WES in the multiplex family and affected offspring of trios. Subsequently, we undertook a case-control study to investigate association between a potential risk gene and schizophrenia. A rare missense variation in UNC13B was identified by WES in multiplex family. Resequencing UNC13B coding regions identified five rare missense variations. In the case-control study, there were no significant association between rare missense UNC13B variations and schizophrenia. The present study did not provide supportive evidence for the contribution of UNC13B to susceptibility to schizophrenia in the Japanese population.
