title: [Association between depression and G72 gene polymorphism].
abstract: OBJECTIVE
  To investigate the association between G72 gene polymorphisms and depression,and to probe the difference of G72 gene polymorphisms between depression with and without mixed family history.
  
  
  METHODS
  The polymorphisms of G72 gene (rs947267 and rs2181953) were detected by PCR technique in 100 depressive patients without mixed family history, 50 depressive patients with mixed family history and 86 normal controls.
  
  
  RESULTS
  (1) The frequencies of rs947267 genotypes and alleles in female depressive patients without mixed family history were significant different to the controls (P=0.017 and P=0.008), the OR scores were 0.300 (A/A, P=0.010), 0.456(A, P=0.008) and 2.195(C, P=0.008) respectively; but in male patients there were no significant differences to the controls (P>0.05). (2) The frequencies of rs2181953 genotypes and alleles in the depressive patients without mixed family history were not significantly different to the controls regardless of sex (P>0.05). (3) The frequencies of rs947267 and rs2181953 genotypes and alleles in the depressive patients with mixed family history were not significantly different to the controls regardless of sex (P>0.05).
  
  
  CONCLUSIONS
  The G72 gene polymorphism may be associated with female depressive patients without mixed family history,C allele of rs947267 may be the risk factor.
