Research Abstract

Several epidemiological studies suggests that the genetic risk has significant influence of susceptibility for schizophrenia. Therefore a large number of genetic studies targeting common variants has been carried out, however small number of the risk variants were discovered by such studies. With the progress of next generation sequencing methodology, detecting of rare risk variant is topic for schizophrenia genetics. In this study, we conducted case-control analysis of target resequencing (about 300 genes) and examined burden of rare variants (nonsense or insertion/deletion).
We found no significant enrichment between schizophrenia and controls, but detected trend for significance of over-representation in early-onset of schizophrenia.
