background: cytochrome p450 2c19 (cyp2c19) is important in metabolism of wide range of drugs. cyp2c19*17 is a novel variant allele which increases gene transcription and therefore results in ultra-rapid metabolizer phenotype (urm). distribution of this variant allele has not been well studied worldwide. the aim of present study was to investigate allele and genotype frequencies of cyp2c19*17 in...
background: angiotensin i converting enzyme (ace) is a zinc metalloproteinase, converts ang-i to ang- ii, a pro-inflammatory agent which may contribute to pathophysiology of some diseases like type 2 diabetes. objective: to investigate the relationship between ace i/d polymorphism and type 2 diabetes in 261 iranian casecontrol pairs. methods: 170 patients (85 type 2 diabetics with nephropathy a...
Disorder in re-methylation process of homocysteine to methionine due to mutation in betaine homocysteine methyltransferase enzyme (BHMT) coding gene, leads to decrease in S-adenosyl methionine (SAM) synthesis which takes part in DNA methylation as a methyl donor. As a result, it can promote hypo-methylation of DNA, chromosome instability, and chromosome missegregation, which in turn is one of t...
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...
in this study, effect of two genotype imputation strategies, relatedness between reference panel and test populations and minor allele frequency on imputation error rate were examined with using a stochastic simulated population. reference panel and test populations were composed of 1,000 and 500 individuals, respectively. individuals in the reference panel were genotyped with using a high and ...
Background and Objective: Prostate cancer is among the five common cancers in males. It is second cancer in terms of the age-standardized rate (ASR) (ASR=16.6) in Iran. The rs2735839 G/A, an intergenic polymorphism is located on chromosome 19q13.33 at 600 base pairs of the KLK3 gene untranslatable region. This gene which codes prostate-specific antigen (PSA) is used in the screening and diagnos...
Introduction & Objective: Adiponectin exerts anti-tumor effect through connection to its receptor. Some studies have shown that polymorphism in Adipor1 results in insulin resistance, diabetic type 2 and colorectal cancer (CRC). The purpose of this study is to investigate the incidence mutant allele of adiponectin receptor 1 polymorphism rs2275738 and to examine the association of genetic vari...
Background and Objective: Alopecia Areata (AA) is a multifactorial disease characterized by hair loss especially from the scalp affecting approximately 5.3 million people. Since major histocompatibility complex (HLA) region is considered to be associated with AA susceptibility, the effect of HLA-DQB1*3 allele frequency was investigated in the present study in AA patients and their respective co...
there are several known and unknown factors for unexplained recurrent spontaneous abortion (ursa). among them, complement regulatory protein cd46 plays a pivotal role in preventing uncontrolled activation of complement and successful continuation of pregnancy. we aimed in this study to investigate the possible association of cd46 ivs1-1724 c>g polymorphism with rsa in iranian women. 141 women w...
