B. Kortner et al., Lack of association between a human beta-2 adrenoceptor gene polymorphism (gln27glu) and morbid obesity, INT J OBES, 23(10), 1999, pp. 1099-1100
OBJECTIVE: To determine the frequency of the gln27glu polymorphism in the b
eta-2 adrenoceptor gene in patients with morbid obesity.
SUBJECTS: 243 patients with morbid obesity (mean body mass index 51.6) and
199 healthy blood donors.
RESULTS: The same frequency, 0.42, of the glu allele was observed in both g
roups. Neither the incidence in obese women (0.41, n = 197) compared to con
trol women (0.43, n = 61), nor that in obese men (0.44, n = 46) compared to
control men (0.41, n = 138) was significantly different. The difference in
frequency between obese men and women, 0.44 vs 0.41 was not significant (P
= 0.68). Genotype information from the families of 18 of the obese patient
s showed no association between the glu27 allele and BMI.
CONCLUSIONS: We find no evidence for a role of the glu27 Variant in the bet
a-2 adrenoceptor gene in the development of morbid obesity.
