Roles of Beta2- and Beta3-Adrenoceptor Polymorphisms in Hypertension and Metabolic Syndrome
Table 5
Confounding variables considered to cause the discrepancy of the relationships between -adrenoceptor polymorphisms and phenotypes of hypertension and metabolic syndrome in obesity.
In lean subjects, 2-AR polymorphisms linked to obesity and obesity-related hypertension, but in obese subjects, 2- and 3-AR polymorphisms relate to obesity and obesity-related hypertension.
Morbid obesity is linked with 3-AR polymorphisms, but overweight or mild obesity is not associated with those.
Interaction between 1- and 2-AR polymorphisms with changes in BMI was observed in men only, while in women an interaction between 1- and 3-AR polymorphisms was observed in a longitudinal over a 24-year period large cohort study.
