Genetic basis of individual differences in the response to small-molecule drugs in yeast.

@article{citeulike:1143860, abstract = {Individual response to small-molecule drugs is variable; a drug that provides a cure for some may confer no therapeutic benefit or trigger an adverse reaction in others.
