Abstract
The present invention relates to a method and a system for selecting a drug customized on the basis of individual protein information by using individual genome sequences. The method and the system of the present invention can predict the individual side effects or danger of a certain drug by analyzing the sequence of the exon region of a gene encoding various proteins involved in the pharmacokinetics or pharmacodynamics of a predetermined drug or drug group, and have high reliability and are widely applicable and universal.
