초록

한국인에서 강박장애와 COMT 유전자 다형성 사이에 연관성이 없었다. 그러나, COMT의 H 대립형질과 강박장애 군에서 공존하는 우울증상 척도가 유의한 연관성을 보인 현상은 COMT 유전자의 다형성이 강박장애의 공존 우울증상에 영향을 미칠 수 있는 가능성을 시사한다고 생각된다.

Abstract

Objectives:The definite cause of obsessive-compulsive disorder (OCD) is still unknown. Evidences from familial, twin and segregation studies support the role of a genetic factor. There are also growing evidence indicating that OCD has specific neurochemical and neuroanatomical basis. Derived from the effectiveness of treatment with dopamine receptor blocker in certain part of OCD patients (eg. SSRI treatment-resistant OCD), several candidate genes related to dopamine dysregulation have been hypothesized to play an important role in the development of OCD. One of them is the Catechol-O-Methyltransferase (COMT) gene. The aim of this study was to investigate the association between COMT and OCD in Korean population. Methods:124 OCD patients and 170 normal controls participated in this study. Genomic DNA was extracted from their blood. The genotypes and allele frequencies of the COMT polymorphism between OCD group and control group were compared. We investigated the association between severity of OCD assessed by Yale-Brown obsessive compulsive symptom scale (YBOCS) and Hamilton depression rating scale (HDRS) scores and COMT polymorphism. Results:In this case-control study, we could not find any association between COMT gene polymorphism and development of OCD. In OCD group, patients with H/H genotype had significantly higher scores for the HDRS than those with H/L or L/L genotype. Conclusion:In this study, there was no difference in genotype distributions of COMT between OCD and control groups. However, H/H genotype of COMT gene polymorphism might be related to depressive symptoms in OCD patients. (J Korean Neuropsychiatr Assoc 2006;45(5):444-452)
