Abstract
1. Objectives As a basic trial for identification of Sasang constitutional gene marker, we genotyped and analysed statistical relationships of STR(short tandem repeat) alleles and its distribution in each constitution. 2. Methods After obtaining basic constitutional data with questionnaire (QSCC II), decision of constitution was made by 3 different constitution specialists' diagnosis, and only the samples of specialists' agreement of each constitution by discussion were taken into this research. Using multiplex PCR kit, total 146 constitutional samples were amplified in 16 autosomal STR marker, genotyped, and analysed statistically. Among 16 markers, 15 were analysed in this study excluding the amelogenin marker is used for in gender identification. 3. Results and Conclusions It is difficult to determine the relationship between constitution and STR marker as the sample size is small, however, Penta D and vWA were shown to be related statistically with constitution. It has been know that STRs has no genetic informations, however there are some recent research results showing STRs as a regulatory element, relationship between microsatellite instability and repeat number and size, and post-transcriptional sigualing. STRs which is not known about its function currently, are proposed to have function and/or regulatory activities anyhow with Sasang constitution. It is believed that the results of this study can halp determine and deatify the markers related to Sasang Constitutional Medicien.
