Brief Summary

This main purpose of this study is to understand the difference and distribution of drug-metabolizing enzyme genetic polymorphisms among Taiwan ethnicities. The subjects of study include Atayal, Pawlan, Yami, Tsou, Ami, Minnan and Hakka. We anticipate establishing a reference for the clinical medication in various ethnic groups according to the difference and distribution of the genetic polymorphisms.
