[์˜๋ฌธ]Metabolic syndrome, which is one of the most prevalent diseases, is a cluster of symptoms associated with ischemic heart disease, obesity and diabetes. Several factors are identified for increased incidence and personal genetic background is also enrolled in pathogenesis. To explain inter-personal differences, single nucleotide polymorphisms are widely used. In this study, association of risk factors and several SNPs in RBP4, HNF-1ฮฑ, and IL-6 were analyzed. From Korean Genomic Research Cohort sample, 100 normal persons, 80 persons with metabolic syndrome, 67 persons with diabetes, and 40 persons with metabolic syndrome and diabetes were included in this study. Genomic DNAs were used for SNP genotyping with Tm-shift assay. Target SNPs were RBP4 -803G/T, HNF-1ฮฑ 401A/G, HNF-1ฮฑ 572A/G, and IL-6 -174G/C. I found several points with statistically significant : 1) SNPs of HNF-1ฮฑ 572 were not independent between the groups of normal vs type 2 diabetes, metabolic syndrome vs type 2 diabetes, and normal vs metabolic syndrome and type 2 diabetes. 2) When categorized into two genotypes of wild carrier and mutant homozygous, HNF-1ฮฑ 572 were significantly distributed in normal vs type 2 diabetes, nomal vs metabolic syndrome, metabolic syndrome vs diabetes, and metabolic syndrome vs metaboic syndrome and type 2 diabetes. 3) When categorized into two genotypes of wild homozygous and mutant carrier, HNF-1ฮฑ 401 and 572 were statistically significant in normal vs metabolic syndrome and normal vs type 2 diabetes, respectively. 3) Mutant homozygous type of RBP4 803 was not found and there was no statistical significace between wild homozygous and heterozygous SNPs. 4) Any mutant mutant of IL-6 -174 were not confirmed in this study. 5) Several markers associated with diabetes and metabolic syndrome were different according to SNPs, but the results were not constant among disease groups. Taken together, we found a few different pattern of SNPs in this study, for example, there is no mutant IL-6 -174, and although genetic factors are seemed to be related in pathogenesis of diabetes and metabolic syndrome in a part, environmental factors might be more associated ones.ope
