BACKGROUND: At present, the patient preparation for IVF needs to undergo a series of planned tests, including the genotyping of single nucleotide polymorphism (SNP) alleles of some genes. In former USSR countries, such investigation was not included in overwhelming majority of health insurance programs and paid by patient. In common, there are prerequisites to the study of more than 50 polymorphisms. An important faced task is to determine the optimal panel for SNP genotyping in terms of price/number of SNP...

OBJECTIVE: Genes encoding key elements of the renin-angiotensin-aldosterone system (RAAS) cascade have been previously but inconsistently associated with blood pressure. Sex-dependency might be important here and functional genetic polymorphisms might exhibit epistatic effects. DESIGN AND METHOD: We assessed variation in the genes encoding renin (REN), angiotensinogen (AGT), angiotensin converting enzyme (ACE), angiotensin II type 1 receptor (AGTR1) and aldosterone synthase (CYP11B2)...

BACKGROUND: With an increase in the discovery of newer genetic loci/polymorphisms in complex multifactorial diseases, there is also an increased need for methods that can simultaneously genotype multiple loci in a cost-effective manner. Using coronary artery disease (CAD) as a model, the study aimed to develop an in-house multilocus assay for simultaneous detection of 17 genetic variants in 11 genes implicated in CAD. METHODS: A multiplex polymerase chain reaction (PCR)-based reverse line blot hybridization (MPCR-RLBH) approach was used, where each DNA sample was amplified using two separate MPCRs, and the alleles were genotyped using covalently immobilized, amino-linked sequence-specific oligonucleotide probes using an enhanced chemiluminescence system...

Endometrial cancer (EC) is the most common gynaecological malignancy and its incidence is increasing. Dysregulation of the endometrial renin-angiotensin system (RAS) could predispose to EC; therefore, we studied the prevalence of RAS single nucleotide polymorphisms (SNPs) in Australian women with EC. SNPs assessed were AGT M235T (rs699); AGTR1 A1166C (rs5186); ACE A240T and T93C (rs4291, rs4292) and ATP6AP2 (rs2968915). They were identified using TaqMan SNP Genotyping Assays. The C allele of the AGTR1 SNP (rs5186) was more prevalent in women with EC (odds ratio (OR) 1...

The rennin-angiotensin-aldosterone system (RAAS) is a critical pathway in regulating blood pressure and salt/water homeostasis, possessing an intimate relationship with the development of systemic artery hypertension (SAH). Once hypertension is considered a risk factor for coronary artery disease (CAD), the RAAS is also related to this pathology. This investigation aimed to analyse if the frequencies of AGT M235T (rs699) and ACE I/D (rs4646994) polymorphisms are associated with CAD and SAH in African-Brazilians and Caucasian-Brazilians...

Activity of the renin-angiotensin Aldosterone system is increased in patients with heart failure (HF). The Angiotensinogen gene and specifically M235T polymorphism has been linked to susceptibility to hypertension, coronary heart disease and atrial fibrillation. Its role in heart failure is not yet sufficiently demonstrated. The aim of the present study was to assess the association between rs699 (M235T) polymorphism and heart failure in terms of diagnosis and prognosis. We included all patients over 20 years old consulting in the Emergency Department for acute dyspnea...

Many studies have suggested that polymorphisms of three key genes (ACE, AGT and CYP11B2) in the renin-angiotensin-aldosterone system (RAAS) play important roles in the development of blood pressure (BP) salt sensitivity, but they have revealed inconsistent results. Thus, we performed a meta-analysis to clarify the association. PubMed and Embase databases were searched for eligible published articles. Fixed- or random-effect models were used to pool odds ratios and 95% confidence intervals based on whether there was significant heterogeneity between studies...

The common angiotensinogen (AGT) M268T polymorphism (rs699; historically referred to as M235T) has been identified as a significant risk factor for cerebrovascular pathologies, yet it is unclear if healthy older adults carrying the threonine amino acid variant have a greater risk for white matter damage in specific fiber tracts. Further, the impact of the threonine variant on cognitive function remains unknown. The present study utilized multiple indices of diffusion tensor imaging (DTI) and neuropsychological assessment to examine the integrity of specific white matter tracts and cognition between individuals with homozygous genotypes of M268T (MetMet n=27, ThrThr n=27)...
