The Trp64Arg polymorphism of the beta3-adrenergic receptor is not increased in women with preeclampsia.

Objective: Insulin resistance is greater and obesity is more common in women with preeclampsia. The Trp64Arg polymorphism in the beta(3)-adrenergic receptor is associated with these metabolic changes. This study investigated whether the Trp64Arg polymorphism is more common in women with preeclampsia.
