title: [The role of urotensin II gene in the genetic susceptibility to type 2 diabetes in Chinese population].
abstract: OBJECTIVE
  To investigate the relationship between the polymorphism of site rs228648 in urotensin II gene and the genetic susceptibility to type 2 diabetes in Han people.
  
  
  METHODS
  Genotyping was conducted to investigate the polymorphism of site rs228648 (G-A) in urotensin II gene among 166 unrelated type 2 diabetic subjects (case group 1), 87 probands from 87 families of type 2 diabetics (case group 2), and 121 non-diabetic normal controls (control group).
  
  
  RESULTS
  1) The frequency of "G" allele of site rs228648 was 62.3% and 75.3% in case group 1 and case group 2 respectively, significantly higher than that in the control group (50.4%, P = 0.004 and P < 0.001). 2) The frequency of G/G genotype of rs228648 was 35% and 53% in case group 1 and case group 2 respectively, significantly higher than that in the control group (24%, P < 0.05 and P < 0.01). The odds ratio was 1.86, P = 0.041 in the case group 1 and 4.03, P < 0.001 in the case control 2 after adjustment by sex, age and BMI.
  
  
  CONCLUSIONS
  Urotensin II gene may contribute to the genetic susceptibility to type 2 diabetes in Han population.
