Association of A Common Haplotype of Hepatocyte Nuclear Factor 1α With Type 2 Diabetes in Chinese Population

Objective To analyze the association of variants of hepatocyte nuclear factor-1α (HNF-1α) gene with type 2 diabetes in Chinese population. Methods In 152 unrelated type 2 diabetes patients and 93 unrelated controls, eleven single nucleotide polymorphisms (SNPs) were identified and genotyped. Statistical analyses were performed to investigate whether these SNPs were associated with diabetes status in our samples. Results In the individual SNP study, no SNP differed significantly in frequency between type 2 diabetes patients and controls. In the haplotype analysis, two haplotype blocks were identified. In haplotype block 1, no evidence was found between common HNF-1α haplotypes and type 2 diabetes. However, in haplotype block 2, a common haplotype GCGC formed by four tagging SNPs (tSNPs) was found to be associated with decreased risk of type 2 diabetes (odds ratio OR 0.6011, 95% confidence interval CI 0.4138-0.8732, P=0.0073, empirical P=0.0511, permutation test). A similar trend was also observed in the diplotype analysis, indicating that the increasing copy number of the haplotype GCGC was associated with the decreased frequency of diabetes (P=0.0193). Conclusion The results of this study provide evidence that the haplotype of HNF-1α decreases the risk of type 2 diabetes in Chinese individuals.     

Association of apelin genetic variants with type 2 diabetes and related clinical features in Chinese Hans

Background Apelin is an adipokine that contributes to the pathogenesis of type 2 diabetes. The plasma levels of apelin increased in obese patients and diabetic subjects. This study aimed to investigate the effects of apelin genetic variants on type 2 diabetes and related quantitative traits. Methods We selected three single nucleotide polymorphisms （SNPs） that could capture all common variants in APLN gene region and genotyped them in 1892 type 2 diabetic patients and 1808 normal glucose regulation controls. The clinical features related to glucose metabolism were measured in the controls. The comparison of allele and genotype distribution in the cases and controls were performed by using X2 tests. The association between SNPs and quantitative traits were analyzed using Wilcoxon＇s rank-sum test. Results None of the SNPs or haplotypes showed evidence of association to type 2 diabetes. However, rs2235306 was nominally associated with fasting plasma glucose levels in the male subjects with normal glucose regulation （（4.93±0.03） vs （5.01±0.03） mmol/L, P=0.04）. No significant difference was observed between all three SNPs and other variables. Conclusions APLN SNP rs2235306 was associated with fasting plasma glucose levels in males. It suggests that APLN genetic variants may contribute to clinical features related to glucose metabolism in Chinese population.

脂肪酸结合蛋白2基因多态性与2型糖尿病

Objective To investigate the association between the polymorphism of codon-54 of the fatty acid binding protein 2 (FABP2) gene and patients with type 2 diabetes, and how to infect metabolism of lipoprotein. Methods The Ala54Thr variation of FABP2 was detected by PCR and Hae-Ⅱ digestion in 225 Chinese subjects, including 117 cases of type 2 diabetes mellitus and 108 cases of normal controls. All cases were detected for fasting plasma lipoprotein. Results (1)The polymorphism restriction site of codon-54 of FABP2 gene results in the substitution of threonine(Thr) for alanine(Ala). Of the 117 diabetic patients screened, 64 (54.7%) were heterozygous, 32 (27.4%) were homozygous for Ala-54 allele and 21 (17.9%) were homozygous for the Thr-54 allele. (2)The frequence of genotype Ala54/Thr54 and Thr54/Thr54 significiantly increased in the type 2 diabetes as compared with that in healthy subjects (P:0.018).(3)The odds ratio of FABP2 genotype Ala54/Thr54 and Thr54/Thr54 for the patients with type 2 diabetes was 1.97(95% confidence intervals is 1.13-3.44). (4)The frequency of the FABP2 mutant thr54 allele was similar in men and women (33.3% and 32.0%, respectively, P=0.675). (5)The patients with type 2 diabetes who carry Ala54/Thr54 and Thr54/Thr54 genotype had a significantly higher level of fasting plasma triglyceride (P=0.003) and lower level of high density lipoprotein cholesterol (HDL-C) (P=0.001)than those with the wild-type. Conclusions (1)FABP2 gene polymorphism seems to be significantly associated with type 2 diabetes; the codon-54 of mutant genotypic frequencies were in Hardy-Weinberg equilibrium. (2)The FABP2 ala54thr polymorphism appears to have no significant difference in men and women. (3)FABP2 polymorphism may have a certain contribution to the abnormity of lipoprotein metabolism in individuals.     

Single Nucleotide Polymorphisms in CAPN10 Gene of Chinese People and Its Correlation With Type 2 Diabetes Mellitus in Han People of Northern China

To investigate the distribution of single nucleotide polymorphisms (SNPs) in CAPN10 gene in Chinese population and their relation with type 2 diabetes mellitus in Han people of Northern China. Methods CAPN10 gene was sequenced to detect SNPs in different nationalities of China. Five SNPs were chosen to perform case-control study and haplotype analysis in 156 normal Han people of Northern China and 173 type 2 diabetes. One SNP was also analyzed with transmission-disequilibrium test (TDT) and sib transmissiondisequilibrium test (STDT) in 68 type 2 diabetes pedigrees (37Tpeople). Results A total of 40 SNPs were identified in length of 8 936bp, with an average of 1 in every 223bp. The SNPs in CAPN10 gene did not distribute evenly and the SNPs in Chinese were different from those reported in Mexican American. There was no significantly statistical difference in the allele frequency of the 5 SNPs between case and control, and the haplotype frequencies in the two groups were not significantly different. No positive results was found in TDT and STDT analysis. Conclusions The SNP distribution of CAPN10 gene differs in different nationalities. The studied SNPs in CAPN10 gene may not be the major susceptibility ones of type 2 diabetes mellitus in Han people of Northern China.     

Estrogen receptor alpha gene polymorphism associated with type 2 diabetes mellitus and the serum lipid concentration in Chinese women in Guangzhou

Background Estrogen might play an important role in type 2 diabetes mellitus pathogenesis. A number of polymorphisms have been reported in the estrogen receptor alpha （ERα） gene （also named ESR1）, including the XbaⅠ and PvuⅡ restriction enzyme polymorphisms of ESR1, which may be involved in disease pathogenesis. The aim of this study was to determine whether ER0t gene polymorphisms are associated with type 2 diabetes mellitus and serum lipid level. Methods Two hundred and ninety-nine patients with type 2 diabetes mellitus were compared with three hundred and forty-one health controls of Guangzhou in China, both were male and postmenopausal female residents at 51--70 years. ESR1 genotyping was performed using polymerase chain reaction （PCR） and PvulI and XbaI restriction fragment length polymorphism （PCR-RFLP） analysis. Results ESR1 allelic frequencies of P, p and X, x alleles were 0.408, 0.592; 0.360, 0.640 in the type 2 diabetes mellitus group and 0.318, 0.682; 0.328, 0.672 in the control group, respectively. In case-control study, there was significant difference in PvuⅡ, but not XbaⅠ, allele frequency between the type 2 diabetes mellitus and control groups （P=0.001 and P=0.122）. When the group was separated into men and women, the difference was significant in women （P〈0.001） but not in men （P=0.854） with the PvulI genotype, and the effect of PvulI variant on the development of type 2 diabetes mellitus was improved with aging. In addition, PvulI genotype was associated with blood glucose [fasting blood glucose （FBG）, postprandial blood glucose （PBG）] and serum lipid [total cholesterol （TC） and low density lipoprotein （LDL）-c] concentration in healthy women. Conclusions PvuII polymorphism of ESRI increases susceptibifity to type 2 diabetes mellitus in Chinese Guangzhou women. ESR1 variants may also impact serum lipid metabolism, which might provide a mechanism connecting ESR1 to type 2 diabetes.     

Beta2-adrenoceptor gene variant Arg16Gly is associated with idiopathic ventricular outflow-tract tachycardia

Background Imbalance of the sympathetic nervous system was involved in the pathogenesis of idiopathic ventricular outflow-tract tachycardia （IVOT）. We aimed to investigate whether the major genetic variants in β1-and β2-adrenoceptors and GNB3 C825T were associated with IVOT and verapamil sensitive idiopathic left ventricular tachycardia （ILVT）.Methods Patients with IVOT and ILVT from December 2005 to December 2007 were consecutively enrolled into this study. Controls were randomly selected from the community-based inhabitants. Five genetic variants, Ser49Gly and Gly389Arg in the β1-adrenoceptor, Arg16Gly and Gln27Glu in the β2-adrenoceptor and GNB3 C825T, were genotyped by polymerase chain reaction-restriction fragment length polymorphism analysis.Results A total of 227 patients with IVOT and 110 patients with ILVT were included. Genotyping revealed that the 16Gly allele of Arg16Gly variant of β2-adrenoceptor was associated with a higher risk of IVOT （OR：1.40, 95% CI： 1.12-1.75,P=0.003 in the addictive model and OR：. 1.62, 95% CI： 1.14-2.31, P=0.007 in the dominant model）. Patients with Gly16Gln27 haplotype also had a higher risk of IVOT （OR： 1.38, 95% CI： 1.11-1.73, P=0.012）. Other four variants,including Ser49Gly and Arg389Gly in β1-adrenoceptor, GIn27Glu in β2-adrenoceptor and GNB3 C825T, did not differ between patients with IVOT and controls. In patients with ILVT, no significant difference was found in these five variants compared with controls.Conclusions Arg16Gly in β2-adrenoceptor is significantly associated with IVOT in Chinese Han population. Major genetic variants in β1- and β2-adrenoceptor and GNB3 C825T may not be associated with ILVT. These data suggest a different arrhythmogenic mechanism in IVOT and ILVT.     

Association of GYS1 and β3-AR gene with postprandial hyperglycemia and ser um uric acid in type 2 diabetes mellitus

Objective To determine the relationships of Met416Val and XbaI polymorphism of muscle glycogen synthase (GYS1) gene and Trg64Arg variant of the β3-adrenergic-receptor (β3-AR) gene with type 2 diabetes mellitus (DM) and its intermediate phenotypes in the Chinese population. Methods Polymerase chain reaction-oligonucleotide ligation assay and restriction fragment length polymorphism assay were used to evaluate the GYS1 and β3-AR gene polymorphisms in 102 pairs of case-control Chinese spouses.Results Subjects with Met416Val variant had a significantly higher 2-hour post-glucose level than subjects without this variant had in diabetic group (P=0.032).The Met416Val polymorphism of GYS1 gene was not significantly associated with the risk of type 2 DM (adjusted OR=1.67; 95% CI: 0.73-3.81, P=0.223). Subjects with Trp64Arg variant had a significantly higher serum uric acid level than subjects without this variant had in diabetic group (P=0.034). The combination of BMI and Arg64 allele carrier of the β3-AR gene increased the diabetic risk over four-fold (adjusted OR=4.00; 95%CI: 1.53-10.45, P=0.005).Conclusions In the Chinese population, Met416Val polymorphism is identified in a subgroup of diabetic subjects with high 2-hour post-glucose.It will explain why some diabetic patients appear to be genetically predisposed to developing high postpradial glucose level.The presence of the Arg64 allele in the β3-AR gene may predispose patients to higher serum uric acid level.     

Effect of genetic variants in KCNJ11, ABCC8, PPARG and HNF4A loci on the susceptibility of type 2 diabetes in Chinese Han population

Background KCNJ11, ABCC8, PPARG, and HNF4A have been found to be associated with type 2 diabetes in populations with different genetic backgrounds. The aim of this study was to test, in a Chinese Han population from Beijing, whether the genetic variants in these four genes were associated with genetic predisposition to type 2 diabetes. Methods We studied the association of four representative SNPs in KCNJ11, ABCC8, PPARG, and HNF4A by genotyping them using ABI SNaPshot Multiplex System in 400 unrelated type 2 diabetic patients and 400 unrelated normoglycaemic subjects. Results rs5219（E23K） in KCNJ11 was associated with genetic susceptibility to type 2 diabetes （OR=1.400 with 95% CI 1.117 1.755, P=0.004 under an additive model, 0R=1.652 with 95% CI 1.086 2.513, P=0.019 under a recessive model, and OR=1.521 with 95% Cl 1.089 2.123, P=0.014 under a dominant model） after adjusting for sex and body mass index （BMI）. We did not find evidence of association for ABCC8 rs1799854, PPARG rs1801282 （Pro12Ala） and HNF4A rs2144908. Genotype-phenotype correlation analysis revealed that rs1799854 in ABCC8 was associated with 2-hour postprandial insulin secretion （P=0.005） after adjusting for sex, age and BMI. Although no interactions between the four variants on the risk of type 2 diabetes were detected, the multiplicative interaction between PPARG Pro12Ala and HNF4A rs2144908 was found to be associated with 2-hour postprandial insulin （P=-0.004 under an additive model for rs2144908; and P=0.001 under a dominant model for rs2144908） after adjusting for age, sex and BMI, assuming a dominant model for PPARG Pro12Ala. Conclusions Our study replicated the association of rs5219 in KCNJ11 with type 2 diabetes in Chinese Han population in Beijing. And we also observed that ABCC8 as well as the interaction between PPARG and HNF4A may contribute to post-challenge insulin secretion.
