A single nucleotide polymorphism c.-1639G>A in the promoter region of vitamin K-epoxide reductase (VKORC1) gene has been found to account for most of the variability in response to oral vitamin K antagonist (VKA). Our aim was to study the effect of c.-1639G>A polymorphism on the acenocoumarol dosage requirements in a group of patients under stable anticoagulation, and to estimate the variabilit...

We examined the association between the adiponectin receptor 2 gene and the risk of ischemic stroke. Polymerase chain reaction-restriction fragment length polymorphism was used to detect rs12342 genotypes of the adiponectin receptor 2 gene in 300 ischemic stroke patients and 320 age- and gender-matched healthy controls. In the patient group, the AA, GA, and GG genotype frequencies were 39.3, 42...

Brain-derived neurotrophic factor (BDNF) has been associated with regulation of body weight and appetite. The goal of this study was to examine the interactions of a functional variant (rs6265) in the BDNF gene with dietary intake for obesity traits in the Boston Puerto Rican Health Study. BDNF rs6265 was genotyped in 1147 Puerto Rican adults and examined for association with obesity-related tr...

OBJECTIVE To determine the frequency of the estrogen receptor b gene (ERβ) +1730 G/A polymorphism in infertile women with and without endometriosis and controls. SUBJECTS AND METHODS Case-control study that included 136 women with endometriosis, 69 women without endometriosis and 209 fertile women as controls. The ERβ gene + 1730 G/A polymorphism was identified by RFLP-PCR (Restriction Fragme...

OBJECTIVE To investigate the association of β-fibrinogen gene polymorphism with plasma fibrinogen and allergic purpura nephritis. METHODS We designed a case-control study (334 case and 300 control) to genotype the β-fibrinogen gene -455G/A polymorphism. The genotype and allele frequencies between the case and control group were compared. And we also compared the Fg concentration between diffe...

BACKGROUND Genetic background partly determines the efficacy of interventions to lower blood pressure (BP). The CYP4F2 and CYP4A11 enzymes are renal 20-hydroxyeicosatetraenoic acid (20-HETE) synthases that regulate BP. Gene variants of CYP4F2 and CYP4A11 associate with hypertension and stroke. We showed that a gene variant of CYP4F2 but not CYP4A11 was associated with increased 20-HETE excretio...

The aim of our study was to investigate the association of interleukin-17A (IL-17A) polymorphisms with IL-17A serum levels and risk of ischemic stroke (IS) in a Chinese population. 392 IS patients and 443 controls were included in this study. The polymorphisms of IL-17A gene were determined by Snapshot SNP genotyping assay and DNA sequencing. Serum IL-17A levels were measured by enzyme-linked i...

We conducted an association study between genetic variants of C-type natriuretic peptide gene (CNP) and hypertension in a Japanese population. We found four genetic variants, two in the promoter region, one missense mutation, and one in the 3'-untranslated region (3'-UTR), and genotyped all four variants in 2,006 subjects recruited from the Suita study. One of the variants, G2628A in 3'-UTR, wa...

asthma is a chronic inflammatory and remodeling disorder of the airways, in which many cells, cellular elements, and cytokines play important roles. the role of tumor necrosis factor- α (tnf-α) in asthma is unclear in pakistani population. the aim of this study was to assess the relationship between tnf-α -308 polymorphism and asthma.polymorphism of tnf-α (g-308-a locus; rs 1800629) in 329 asth...

We performed a study to investigate the role of ERCC1 (rs11615, rs2298881, and rs3212986) and ERCC2 (rs13181, rs238406, and rs1799793) polymorphisms in the prognosis of gastric cancer. A total of 346 patients with gastric cancer were recruited between May 2009 and May 2012. Single nucleotide polymorphism genotyping was performed using the Sequenom MassARRAY platform. The GA+AA genotype of ERCC2...
