title: [Association study on the mitochondrial genome region np16181-16193 variation with type 2 diabetes mellitus].
abstract: OBJECTIVE
  To investigate the association of the mitochondrial DNA region np16181-16193 variations with type 2 diabetes mellitus (T2DM).
  
  
  METHODS
  Blood samples of 199 unrelated T2DM patients and 205 normal controls were collected to detect the mitochondrial DNA region np16181-16193 variations by PCR and sequencing, and to analyze the association of the variations with the major clinical symptoms.
  
  
  RESULTS
  The mitochondrial DNA np16181-16193 region is a hypervariable area, with several polymorphisms. Four types of np16181-16193 region variations were found only in T2DM. The 1-hour postprandial blood glucose (P1BG) in the T2DM individuals with np16181-16193 region variations was significantly higher than those without variations (P<0.05), while there was no significant difference in other biochemical parameters (P>0.05).
  
  
  CONCLUSIONS
  The mitochondrial DNA np16181-16193 variations could not be regarded as a risk factor for T2DM.
