Objectives : Sasang Constitutional Medicine is based on the diversity of human beings and medically developing a variation of responses to diseases and medicines. This diversity is categorized into four concerning morphology, physiology, pathology, and pharmacology. It is supposed that sasang constitutional medicine is related the genetic diversity of individuals. Single nucleotide polymorphism is the basic tool to research genetic polymorphism as a landmark of genomes. Each constitution has different processes of pathophysiology and metabolisms to herb medications. In clinical research, the stroke incidence is significantly different by constitution. Methods : We researched whether the polymorphic expression of CCK (rs=2241997) depends on sasang constitution. The [c/t] polymorphism site of promotor region of CCK gene on 3p22-p21.3 was investigated. Results : The allele frequency of [c/t] polymorphism of CCK promotor region was different in constitution groups compared to the average allele frequency of SNP DB. The allele frequencies of Soeumin and Soyangin groups were (c:0.70/t:0.30). and (c:0.71/t:0.29), that of Taeumin group was (c:0.57/t:0.43) and of Taeyangin group was (c:1.00/t:0.00) Conclusions : It was regarded the [c/t] polymorphism of CCK promotor region is available to classify the constitution. However, it is necessary to research about CCK gene polymorphism and more constitution population groups. It is also necessary to research the more functional gene's polymorphism and sasang constitution.
