Disease: Bipolar Disorder
Bipolar Disorder 		0.700 GeneticVariation disease BEFREE Our study suggests that the markers examined thus far in COMT and SLC6A4 are not associated with pediatric bipolar disorder and that if the val66met marker in BDNF is associated with pediatric bipolar disorder the magnitude of the association is much smaller than first reported. 19193231 2009
