title: No association between dopamine D1, D2, and D3 receptor genes and manic-depressive illness.
abstract: BACKGROUND
  The dopaminergic receptor genes are candidate genes for manic-depressive illness (MDI). To test this putative involvement we used a case-control study on samples from the native population of the northwest part of France.
  
  
  METHODS
  Fifty patients for D1 and D2, 61 patients for D3, and 86-223 controls were tested.
  
  
  RESULTS
  No significant association was found between allelic frequencies or genotype counts and MDI, even when the data were pooled with those from published studies.
  
  
  CONCLUSIONS
  Single mutations of either of the studied receptor genes are not major determinants of MDI.
