ABSTRACT

PURPOSE:

The beta-adrenoceptors are pharmacologically classified into beta1-, beta2- and beta3-adrenoceptor. The gene of each subtype has polymorphisms related to their function (beta1-adrenoceptor Ser49Gly, beta2- adrenoceptor Gln27Glu, beta3-adrenoceptor Trp64Arg). The objectives of this study were to analyse the allelic and genotypic distribution of the representative polymorphism of beta-adrenoceptors in preeclampsia and to investigate whether combined genotype of beta-adrenoceptors may be associated with preeclampsia.

METHODS:

Blood samples were collected from a Korean population (159 preeclamptic pregnancies and 168 normotensive pregnancies). The beta1-, beta2- and beta3-adrenoceptor genotypes was determined using polymerase chain reaction-restriction fragment length polymorphism.

RESULTS:

There were no differences in allelic and genotypic distribution of beta1- and beta2-adrenoceptor polymorphisms between the two groups. However, the Arg allele of beta3-adrenoceptor polymorphism were more frequent in preecalmpsia than in controls (P<0.05, OR=1.57, 95% CI=1.01-2.46). Moreover, prevalence of genotype carrying heterozygote of beta3-adrenoceptor polymorphism was increased in preeclampsia compared with controls (P<0.05, OR 1.76, 95% CI 1.06-2.92). When combination of the three polymorphisms were evaluated, pregnancies with the particular combined genotype that is consisted of heterozygote of beta1-, beta3-adrenoceptor and wild homozygote of beta2-adrenoceptor (Ser/Gly, Gln/Gln, Trp/Arg), showed a significant increase in the risk of preeclampsia (P<0.05, OR=3.01, 95% CI 1.12-8.08).

CONCLUSION:

A particular combined genotype (Ser/Gly, Gln/Gln, Trp/Arg) of - adrenoceptors was associated with the risk of preeclampsia.
