Background: Adiponectin, an adipocyte-secreted hormone, is known to have anti-atherogenic, anti-inflammatory, and anti-diabetic properties. In the present study, the association between two common single nucleotide polymorphisms (SNPs) (+45T/G and +276G/T) of ADIOPQ gene and coronary artery disease (CAD) was assessed in the subjects with type 2 diabetes (T2DM). Methods: Genotypes of two SNPs we...
BACKGROUND β2 adrenergic receptor (ADRβ2) polymorphisms including ADRβ2+46G>A have been reported to cause adverse outcomes in mild asthmatics. The extent to which ADRβ2 polymorphisms and in particular their haplotypes contribute to severe asthma is unknown. OBJECTIVE To determine the association of ADRβ2 polymorphisms and haplotypes with asthma severity. METHODS Caucasians (n = 2979) were g...
introduction: β-globin gene cluster haplotypes are useful in diagnosis of particular molecular defects in β-thalassemia, prenatal diagnosis of β-thalassemia, and elucidating population affinities. methods: β-globin gene cluster haplotypes were studied in 150 β-thalassemia minor and 52 healthy in-dividuals from the fars province of iran. dna was extracted from leukocytes of whole blood by phe-no...
Mitochondrial DNA (mtDNA) haplotypes usually are assumed to be neutral, unselected markers of evolving female lineages. This assumption was tested by monitoring haplotype frequencies in 12 experimental populations of Drosophila pseudoobscura which were polymorphic for mtDNA haplotypes. Populations were maintained for at least 10 generations, and in one case for 32 generations, while tests of mt...
CYP11A catalyzes the rate-limiting step in the biosynthesis of sex-steroid hormones. In this study, we employed a systematic approach that involved gene resequencing and a haplotype-based analysis to investigate the relationship between common variation in CYP11A and breast cancer risk among African-Americans, Latinas, Japanese-Americans, Native Hawaiians, and Whites in the Multiethnic Cohort S...
MOTIVATION Killer immunoglobulin-like receptor (KIR) genes vary considerably in their presence or absence on a specific regional haplotype. Because presence or absence of these genes is largely detected using locus-specific genotyping technology, the distinction between homozygosity and hemizygosity is often ambiguous. The performance of methods for haplotype inference (e.g. PL-EM, PHASE) for K...
