BACKGROUND A great deal of effort and expense are being expended internationally in attempts to detect genetic polymorphisms contributing to susceptibility to complex human disease. Techniques such as Linkage Disequilibrium mapping are being increasingly used to examine and compare markers across increasingly large datasets. Visualisation techniques are(More)
BACKGROUND Researchers wishing to conduct genetic association analysis involving single nucleotide polymorphisms (SNPs) or haplotypes are often confronted with the lack of user-friendly graphical analysis tools, requiring sophisticated statistical and informatics expertise to perform relatively straightforward tasks. Tools, such as the SimHap package for(More)
BACKGROUND Interleukin (IL)-18 is a proinflammatory cytokine that has been implicated in several diseases, including atherosclerosis, and increased circulating IL-18 concentrations increase risk of future coronary heart disease (CHD). We evaluated the effect of common variation within the IL18 gene on concentrations of circulating IL-18. METHODS We(More)
Serum high density lipoprotein (HDL) levels are inversely related to the development of coronary artery disease (CAD). Apolipoproteins AI and AII are the major protein constituents of HDL particles. APOAI and APOAII genetic polymorphisms have been proposed to affect transcriptional efficiency of their respective genes, thereby altering serum lipid levels(More)
Asthma, atopy, and related phenotypes are heterogeneous complex traits, with both genetic and environmental risk factors. Extensive research has been conducted and over hundred genes have been associated with asthma and atopy phenotypes, but many of these findings have failed to replicate in subsequent studies. To separate true associations from false(More)
BACKGROUND Cholesteryl ester transfer protein (CETP) inhibitors raise high-density lipoprotein (HDL) cholesterol, but torcetrapib, the first-in-class inhibitor tested in a large outcome trial, caused an unexpected blood pressure elevation and increased cardiovascular events. Whether the hypertensive effect resulted from CETP inhibition or an off-target(More)
The objective of this study was to determine whether single nucleotide polymorphisms (SNPs) in the Interleukin-1 (IL-1) gene family are associated with central obesity and metabolic syndrome in a coronary heart disease population. The IL-1 alpha C-889T (rs1800587) and IL-1 beta +3954 (rs1143634) SNPs were studied in a Western Australian coronary heart(More)
High-density lipoprotein cholesterol (HDL-C) is a known inverse predictor of coronary heart disease (CHD) and is thus a potential therapeutic target. Cholesteryl ester transfer protein (CETP) is a key protein in HDL-C metabolism such that elevated CETP activity is associated with lower HDL-C. Currently available HDL-C raising drugs are relatively(More)
AIMS/HYPOTHESIS Common genetic variants influence plasma triacylglycerol, HDL-cholesterol (HDL-C) and glucose levels in cross-sectional studies. However, the longitudinal effects of these established variants have not been studied. Our aim was to examine the longitudinal associations of four such variants in the apolipoprotein A-V (APOA5), lipoprotein(More)
PARL (presenilin-associated rhomboid-like) is a mitochondrial protein involved in mitochondrial membrane remodelling, and maps to a quantitative trait locus (3q27) associated with metabolic traits. Recently the rs3732581 (Leu262Val) variant was found to be associated with increased levels of plasma insulin, a finding not replicated in a larger cohort. The(More)
