Objective:
To detect the relationship between heroin-dependence and -287 A/G polymorphism of catechol-O-methyltransferase(COMT) gene.
Methods:
Genotype and allele frequencies of -287 A/G polymorphism of COMT gene were examined in 268 heroin-dependent subjects and 177 normal controls.
Results:
Weak but significant difference in genotype of -287 A/G polymorphism of COMT gene was observed between heroin-dependent subjects and controls (chi(2)=7.41, P=0.025), and genotype AA was higher in the former. The frequency of allele A of -287 A/G polymorphism of COMT gene was also significantly higher in heroin-dependent subjects than in the controls (chi(2)=5.69, P=0.017).
Conclusion:
The results suggested that liability to heroin-dependence was associated with -287 A/G polymorphism of COMT gene.
