title: [Study on the association of PPP1R3 gene polymorphism with type 2 diabetes in Han population of Anhui province].
abstract: OBJECTIVE
  To study the association of muscle-specific glycogen-targeting regulatory subunit of the glucogen-bound protein phosphatase 1 (PPP1R3) gene codon 905 Asp/Tyr polymorphism with type 2 diabetes in Chinese Han population in Hefei region of Anhui province.
  
  
  METHODS
  PPP1R3 gene Asp905Tyr polymorphism was detected by polymerase chain reaction and appropriate restriction enzyme (PCR-RFLP) in 262 type 2 diabetic cases and 104 normal controls. Case and control groups were divided into subgroups by body mass index (BMI) 25 kg/m2.
  
  
  RESULTS
  When PPP1R3 gene Asp905Tyr polymorphism was not associated with type 2 diabetes mellitus. When subjects with BMI < 25 kg/m2 and Tyr/Tyr genotypes were used as reference. Subjects with Asp905 and BMI > or = 25 kg/m2 had a 3.69-fold increase of risk suffering from type 2 diabetes (OR = 3.69, 95% CI: 1.38-8.89, P=0.006).
  
  
  CONCLUSIONS
  PPP1R3 gene Asp905Tyr polymorphism did not seem to play a critical role in the development of type 2 diabetes mellitus in Han population of Chinese in Anhui province but interaction between the Asp905 and BMI cause the increase of risk of type 2 diabetes.
