| Research Abstract |
Deficits in prepulse inhibition (PPI) are a biological marker for psychiatric illnesses such as schizophrenia and bipolar disorder. To unravel PPI-controlling mechanisms, we previously performed quantitative trait loci analysis in mice, and identified Fabp7, that encodes a brain-type fatty acid binding protein (Fabp), as a causative gene. FABPs constitute a gene family, of which members FABP5 and FABP3 are also expressed in the brain. In this project, I examined the genetic roles of these FABP genes in schizophrenia and bipolar disorder. FABP7 showed nominal association with bipolar disorder (we previously reported an association of FABP7 with schizophrenia). We could not obtain evidence for associations of FABP5 and FABP3 with either disease.
