Outline of Final Research Achievements

To elucidate the etiology of psychiatric disorders, it is critical to establish appropriate animal models reflecting their pathogenesis. Common marmosets (Callithrix jacchus) have advantages as animal models for psychiatric disorders because the higher function of their brain is similar to that of humans. In this study, we performed genomic analysis of marmosets and aimed to identify pathogenic copy number variations (CNVs) associated the risk of psychiatric disorders, and to examine phenotypes of individuals with these CNVs. As a result of the analysis of 47 marmoset individuals, we identified a very large deletion (8.4 Mb) at chromosome 16 in one individual. CNVs of this size may be associated with the risk of psychiatric disorders in humans. However, we could not do any further examination because phenotype data for this individual was not available.
