allergic asthma is a multifactorial disease, influenced by genetic and environmental factors. recent family-based studies have revealed evidence for linkage of human chromosomes 5q31-33, 12q15-24, 11q13 and 15q23.6 as regions likely to contain genes related to asthma. among the candidate genes in these regions are the genes encoding for human interleukin-4, interleukin-13 and interleukin-16. to...

The aim of the current study was to explore the correlation between serum homocysteine (HCY) levels and the methylene tetrahydrofolate reductase (MTHFR) gene 677C/T polymorphism and coronary heart disease (CHD). We consecutively enrolled 208 patients with CHD confirmed by CTA or coronary angiography from our hospital. An additional 200 healthy volunteers were enrolled as the control group. Seru...

A series of pro-oxidant and antioxidant enzymes, such as the NADPH oxidase system, maintain the redox state in the vessel wall. A major component of NADPH oxidase is p22, which is implicated in atherosclerosis. We prospectively studied the association of the histidine (H)3tyrosine (Y) mutation in p22 with the severity and progression/regression of coronary artery disease (CAD), plasma lipid lev...

The present study determined an association between idiopathic sperm disorders in a local Pakistani infertile male population and the MTHFR C677T polymorphism. After ruling out non genetic factors, a total of 437 idiopathic infertile men including 57 azoospermic, 66 oligospermic, 44 asthenozoospermic, 29 teratozoospermic, 20 oligoasthenospermic and 221 infertile normospermic men were recruited....

background: an association between lung cancer and chemokines has been advocated in the recent years. this study aims at investigating the association between lung cancer and 16c/a single nucleotide polymorphism (snp) (rs. 4359426) in c-c motif chemokine 22 (ccl22) as well as c1014t snp (rs. 2228428) in c-c chemokine receptor type 4 (ccr4), which serves as the receptor for ccl22. methods: genot...

In this paper, we propose a novel mixed-effects model for longitudinal changes of systolic blood pressure (SBP) over time that can estimate the joint effect of multiple sequence variants on SBP after accounting for familial correlation and the time dependencies within individuals. First we carried out agenome-wide association study (GWAS) using chromosome 3 single-nucleotide polymorphisms(SNPs)...

A functional genetic variant consisting of a C825T substitution in the GNB3 gene, encoding for the G-protein beta(3) subunit, has been associated with enhanced G-protein activation and cell growth. The aim of the study was to investigate the association of this polymorphism with left ventricular hypertrophy (LVH) in a sample of patients with essential hypertension. Left ventricular mass was ass...
