Abstract:
Objective:To quantitatively summarize the catechol-O-methyltransferase ( COMT) gene Val158Met polymorphism and the risk of obsessive-compulsive disorder (OCD). Methods:We searched databases including PubMed, Embase, Weipu and Wanfang for randomized controlled trials (RCTs) investigating the association between COMT gene polymorphisms and OCD up to November 1, 2023. Studies that reported genotype frequencies for both OCD patients and general healthy controls were included. Stata11 software was used to calculate pooled odds ratios ( OR) with 95% CI, perform heterogeneity test, and assess publication bias. Results:19 studies with 2, 393 OCD patients and 4, 134 healthy controls were included. The overall results showed that the Val158Met polymorphism was associated with OCD patients (allele model: OR=1.10, 95% CI: 1.02-1.20, P=0.016; homozygote model: OR=1.25, 95% CI:1.05-1.49, P=0.014; recessive model: OR=1.18, 95% CI:1.01-1.37, P=0.040). In the ethnic-stratified analysis, this significant association was mainly observed in Caucasians (allele model: OR=1.17, 95% CI:1.06-1.30, P=0.003; homozygote model: OR=1.35, 95% CI: 1.08-1.67, P=0.008; recessive model: OR=1.21, 95% CI: 1.01-1.44, P=0.041; dominant: OR=1.20, 95% CI: 1.01-1.43 P=0.040), but not in Asians. In gender-stratified analysis, Met-homozygote was associated with male OCD ( OR=1.75, 95% CI: 1.00-3.04, P=0.049). Moreover, the additional analysis found that the risk of OCD was significantly increased in Caucasian males (allele model: OR=1.48, 95% CI: 1.08-2.03, P=0.014; heterozygote model: OR=1.41, 95% CI: 1.03-1.93, P=0.030; dominant model: OR=1.60, 95% CI:1.08-2.38, P=0.020). Conclusion:This meta-analysis suggests that the COMT gene Val158Met polymorphism is associated with an increased risk of OCD in males, particularly in Caucasian males.
