| Outline of Final Research Achievements |
95 obsessive and compulsive disorder (OCD) patients and 93 healthy controls (HCS) were genotyped with L- and s- types polymorphisms of 5HTT-LPR, 5HTT-VNTR, DAT-VNTR, D4-120、D4-48. As a result, any genetic polymorphisms were observed no significant difference between OCD patients and HCs. Magnetic resonance imaging examinations of 40 OCD patients and 40 HCs were carried out. As of genotype-diagnosis interaction, though no voxels survived multiple comparison, we observed a tendency that 5-HTTLPR polymorphism with OCD patients had stronger effects on the right frontal pole than those in HCs. Moreover, we investigated the differences in terms of DNA methylation profile of HTR2A gene and COMT gene between 48 OCD patients and 48 HCs.
We found a significant difference between the OCD patients and HCs in the percent methylation of the COMT gene.
