Abstract
BACKGROUND: To explore the correlation between FTO (fat mass and obesity associated) gene, which is associated with 3 single nucleotide polymorphisms (SNP) of fat mass and obesity, type 2 diabetes and body mass index (BMI) in the Uygur population in northwest China. METHODS: A total of 849 Uygur patients with type 2 diabetes mellitus were selected from the hospitalized patients in the First Affiliated Hospital of Xinjiang Medical University, the First People's Hospital of Kashi and the hospitals in the Turpan areas. At the same time, 873 cases of healthy persons who conducted a medical checkup in the physical examination centre of the above hospitals were enrolled as controls. The present investigation used the case-control research method, and physical examination and biochemical index determination were carried out. The Sequenom MassARRAY technology was employed in the detection of 3 SNP loci of the FTO gene. The representative population of each SNP in the control group was analyzed by Hardy-Weinberg law. The differences of each clinical parameter in the two groups were analyzed by t-test analysis. The differences of genotype and allele of each SNP in the two groups were analyzed by χ(2) test. RESULTS: BMI, waistline (WL), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG), total cholesterol (TC), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in the type 2 diabetes group were higher than those in the control group, while the high density lipoprotein (HDL) and low density lipoprotein (LDL) were lower than those of the control group; 2. The allele frequency of A of rs8050136 and rs9939609 in the type 2 diabetes mellitus group was higher than that of the control group. The BMI of the whole population and type 2 diabetes group with genotype C/A+A/A of rs8050136 was higher than that in C/C group, and the BMI with genotype T/A+A/A of rs9939609 was higher than that in group T/T. Stratification was conducted on BMI according to the normal, overweight and obesity criteria. There were significant differences in the distribution of genotype frequency of rs9939609 in the type 2 diabetes group and the control group of the normal BMI group. CONCLUSION: Single nucleotide mutation of rs7195539 in FTO gene may be a protective factor against the Uygur type 2 diabetes. Single nucleotide mutations of rs8050136 and rs9939609 may be associated with the Uygur type 2 diabetes and obesity, with A as a potential risk allele. The gene polymorphism of rs8050136 may correlate with type 2 diabetes mellitus through the function of BMI, while the correlation between rs9939609 gene polymorphism and type 2 diabetes is not depending from BMI.
