Among the 6 SNPs and the genetic risks scores (GRS), the minor alleles of HNF1Ars1169288 (odd ratio (OR) = 1.18, 95% confidence interval (CI) 1.05-1.33, P = 0.006) and MADD-FOLH1 rs7395662 (OR = 1.20, 95% CI 1.07-1.36, P = 0.002) as well as the GRS (P = 1.06 × 10(-5)) were significantly associated with increased risk of CAD after false discovery rate (FDR) correction.
We examined the role of hepatic nuclear factor-1 alpha (HNF1a) gene polymorphism on coronary artery disease (CAD) traits in 4631 Saudi angiographed individuals (2419 CAD versus 2212 controls) using TaqMan assay on ABI Prism 7900HT sequence detection system.
We investigated the association of the rs2259816 polymorphism in the HNF1A gene with the circulating level of C-reactive protein and the hazard of coronary artery disease in the LURIC Study cohort.
We identified one new CAD risk locus on 3q22.3 in MRAS (P = 7.44 x 10(-13); OR = 1.15, 95% CI = 1.11-1.19), and suggestive association with a locus on 12q24.31 near HNF1A-C12orf43 (P = 4.81 x 10(-7); OR = 1.08, 95% CI = 1.05-1.11).
The HNF1ASer486Asn and/or Ile27Leu variants were also associated with increased risk of subclinical coronary atherosclerosis in Coronary Artery Risk Development in Young Adults and with incident coronary heart disease in Cardiovascular Health Study.
Based on the recent genetic findings as well as delineation of the role of HNF1-alpha in regulating the expression of the CRP gene, it appears that this transcription factor may play a key role in linking metabolic and inflammatory pathways underlying the pathogenesis of coronary heart disease.
Coronary heart disease was more common in MODY3 than in IDDM (16 vs 4.5%; p < 0.02) but less common than in the older NIDDM patients (33.3%; p < 0.02).
