Abstract
BACKGROUND Variants in the Hepatocyte Nuclear Factor 1 Alpha gene (HNF1A) are associated with lipoproteins levels and type 2 diabetes. In this study, we aimed to assess the association of HNF1A gene and haplotypes with the metabolic syndrome (MetS) and its components through an association study in the Tunisian population as well as by a meta-analysis. METHODS A total of 594 Tunisian individuals were genotyped for three variants (rs1169288, rs2464196 and rs735396) located in HNF1A gene using KASPar technology. Statistical analyses were performed with R software. The association was furthermore evaluated through a meta-analysis of our results with those obtained in a Moroccan population. RESULTS Our results showed no association between HNF1A variants and MetS in the Tunisian population. However, a significant association was observed between the variant rs735396 and a higher waist circumference. The stratified analysis according to the sex highlighted a significant association between the variant rs1169288 and high cholesterol levels only in women. Similarly, Haplotype analysis showed an association between the HNF1A minor haplotype and high total cholesterol mainly in women. Finally, our meta-analysis showed no association between HNF1A variants and MetS. CONCLUSIONS Our findings exclude the involvement of the three HNF1A variants rs1169288, rs2464196 and rs735396 in the susceptibility to MetS in our studied Tunisian population but emphasize the role of these variants in the cholesterol homeostasis with sex-specific differences, which may serve to rise clinical consideration to early statin therapy in women carrying these genetic variants.

Abstract
OBJECTIVES Increasing type 2 diabetes in Aboriginal communities across North America raises concerns about metabolic syndrome in these populations. Some prevalence information for American Indians exists, but little has been available for Canada's First Nations. STUDY DESIGN We screened 60% of the eligible population of a single First Nation in Alberta for diabetes, pre-diabetes, cardiovascular risk, and metabolic syndrome. METHODS NCEP/ATP III and IDF criteria were used to identify metabolic syndrome in participants aged > or = 18; modified NCEP/ATP III criteria were used for participants aged < 18. Logistic regression identified factors associated with the metabolic syndrome. RESULTS 297 individuals were screened (176 adults, 84 children/adolescents, with complete data). 52.3% of adults had metabolic syndrome using NCEP/ATP III criteria, and 50% using IDF criteria. 40.5% of individuals aged < 18 had the condition. Waist circumference was the most prevalent correlate. Bivariate analysis suggested that age, BMI, weight, Alc, LDL-C, ADA risk score and activity pattern were associated with metabolic syndrome. CONCLUSIONS Our data represent the first available for Western Cree and are consistent with prevalence reported for Aboriginal populations in Ontario and Manitoba. High rates of obesity, pre-diabetes and metabolic syndrome for participants aged < 18 raise concerns about future prevalence of diabetes and cardiovascular disease.

Abstract
OBJECTIVES To determine the prevalence of 'hypertriglyceridemic waist' (HTGW) in Oji-Cree, to examine its interaction with hepatic nuclear factor-1alpha (HNF1A) in association with type 2 diabetes, and to characterize its putative genetic determinants. METHOD The presence or absence of HTGW was determined in 522 Oji-Cree subjects (223 males, 299 females), >or=18 years of age, in whom physical measurements and fasting plasma analyte concentrations were gathered, and a 75-g oral glucose tolerance test was administered, as part of a cross-sectional study. Subjects were genotyped for HNF1A codon 319, angiotensinogen (AGT) codons 174 and 235, G-protein beta3-subunit (GNB3) nucleotide 825, fatty acid-binding protein (FABP2) codon 54, nucleotides -455 and -482 of the apolipoprotein (apo) C-III (APOC3) promoter, and a 5-bp insertion/deletion polymorphism within the 3'-untranslated region of protein phosphatase 1 regulatory subunit 3 (PPP1R3). RESULTS The unadjusted prevalence of HTGW in Oji-Cree adults was 20.5%, with more males affected than females (27.8 vs 15.1%, P=0.0004). Logistic regression analysis, adjusted for age and gender, showed type 2 diabetes was associated with both HNF1A G319S (odds ratio (OR) 4.85, 95% CI 2.45, 9.58) and HTGW (OR 4.96, 95% CI 2.49, 9.88). When the HNF1A mutation and HTGW were present in combination, the OR for type 2 diabetes was markedly increased (OR 43.2, 95% CI 12.4, 150). In women only, both GNB3 825C>T and FABP2 A54T genotypes were significantly associated with HTGW (OR 2.02, 95% CI 1.01, 4.05 and OR 1.95, 95% CI 1.01, 3.74, respectively). CONCLUSIONS HTGW is prevalent in Oji-Cree, especially in men. The ORs for type 2 diabetes were similar ( approximately 5-fold) for subjects with either the presence of HTGW or the private HNF1A G319S mutation. These two independent risk factors acted synergistically to confer an even greater increased risk of type 2 diabetes.
