Abstract
OBJECTIVE Our aim was to analyse the association with multiple sclerosis of the genetic markers of autoimmune disorders identified in genome-wide association studies in ethnically homogenous groups of Russians and Tatars residing in the Republic of Bashkortostan. MATERIAL AND METHODS We performed genotyping of the genetic variants rs2069762 in IL2 gene, rs759648 in PVT1 gene, rs1800682 in FAS gene and rs12708716 in CLEC16A gene in the study group consisting of 1724 people (547 patients with multiple sclerosis, 1177 representatives of the control group). We analysed the association of the studied genetic markers with multiple sclerosis using logistic regression under additive genetic model implemented in PLINK program with sex a covariate. RESULTS In the group of Tatars, we detected an association of PVT1 rs759648*Callele with multiple sclerosis (OR=1.42, p=0,023). Meta-analysis of the study results in the two ethnic groups we confirmed the association of the PVT1 rs759648*C allele with the disease (random effects model and fixed effect model: OR=1.29, p=0,018). CONCLUSION Our results provide an evidence of an association between multiple sclerosis and the PVT1 rs759648 allele in the populations of Russian and Tatars from the Republic of Bashkortostan. No association with any other studied polymorphic variant was found in the two ethnic groups.

The association between eating behavior and polymorphisms in GRIN2B, GRIK3, GRIA1 and GRIN1 genes in people with type 2 diabetes mellitus. Mol Biol Rep 2020; 47:2035-2046. [PMID: 32037472 DOI: 10.1007/s11033-020-05304-x] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2019] [Accepted: 02/04/2020] [Indexed: 12/13/2022]
Abstract
Excess body weight is the main risk factor of type 2 diabetes. Recent studies have shown that psychological and behavioral factors affect weight. Additionally, emerging evidence indicates that polymorphisms of neurotransmitter genes can impact eating behavior. The aim of this study was to detect the associations between SNPs in glutamatergic system genes and type 2 diabetes in the ethnic group of Tatars origin living in the Republic of Bashkortostan (Russian Federation). In our case-control cross-sectional study, 501 patients with type 2 diabetes (170 men and 331 women, 60.9 ± 9.2 years old (mean ± SD), BMI 30.9 ± 3.9 kg/m2 (mean ± SD) of Tatar ethnicity, and a control group of 420 Tatars (170 men and 250 women, 56.3 ± 11.6 years old (mean ± SD), BMI 24.4 ± 4.3 kg/m2 (mean ± SD), were genotyped for five SNPs in four glutamatergic genes (GRIN2B, GRIK3, GRIA1, GRIN1). Three SNPs were associated with type 2 diabetes: rs7301328 in GRIN2B [odds ratio adjusted for age, sex and BMI (ORadj) = 0.77 (95% CI 0.63-0.93), padj = 0.0077], rs1805476 in GRIN2B [ORadj = 1.25 (95% CI 1.03-1.51), padj = 0.0240], and rs2195450 in GRIA1 [ORadj = 1.35 (95% CI 1.02-1.79), padj = 0.0340]. Regression analysis revealed that rs1805476 in GRIN2B was associated with LDL level, glomerular filtration rate, BMI (p = 0.020, p = 0.012 and p = 0.018, respectively). The SNP rs7301328 in GRIN2B was associated with triglyceride levels and HbA1c (p = 0.040, p = 0.023, respectively). These associations were not significant after Bonferroni correction. We found the association between rs534131 in GRIK3, rs2195450 in GRIA1, rs1805476 in GRIN2B and diabetic retinopathy (p = 0.005, p = 0.007, p = 0.040, respectively); rs7301328 in GRIN2B was associated with hypertension (p = 0.025) and cerebrovascular disease (p = 0.013). The association between rs534131 of GRIK3, rs2195450 of GRIA1 genes and diabetic retinopathy remained significant after Bonferroni correction. The SNPs rs6293 in GRIN1 was significantly associated with eating behavior in patients with type 2 diabetes (p = 0.01). Our results demonstrate that polymorphic variants of glutamatergic genes are associated with eating behavior and diabetic complications in Tatar ethnic group residing in the Republic of Bashkortostan. We detected novel associations of the polymorphic loci in GRIN1 (rs6293) gene with external eating behavior in type 2 diabetes patients, GRIK3 (rs534131) and GRIA1 (rs2195450) genes with diabetic retinopathy.

Abstract
The amelogenin gene encodes dental enamel protein and is present in humans in two forms - AMELX and AMELY, located on the X- and Y-chromosomes, respectively. This rare case depicts a partial deletion of the AMELY gene. In the Into-Stil LLC laboratory, we performed the genetic testing of the DNA samples extracted from buccal epithelial cells of the alleged father and the disputed child (a boy). Genotyping was carried out using COrDIS Plus ('Gordis', Russian Federation) and AmpFLSTR Identifiler Direct PCR Amplification ('Applied Biosystems', USA) Kits. Our findings have demonstrated that both the alleged father and the disputed child lacked the fragments corresponding with the AMELY gene. Using both STR-systems, we detected, in the disputed child's genome, the allele formally identical to the allele in the genome of the alleged father. Further analysis using the COrDYS ('Gordis', Russian Federation) kit allowed us to detect the amplified fragments corresponding with all the STR loci of Y chromosome, except DYS576 and DYS449, which confirmed that both studied individuals belonged to male biological sex.

Abstract
BACKGROUND Genome-wide association studies have captured a large proportion of genetic variation related to type 1 diabetes mellitus (T1D). However, most of these studies are performed in populations of European ancestry and therefore the disease risk estimations can be inaccurate when extrapolated to other world populations. METHODS We conducted a case-control study in 1866 individuals from the three major populations of the Republic of Bashkortostan (Russians, Tatars, and Bashkirs) in Russian Federation, using single-locus and multilocus approach to identify genetic predictors of T1D. RESULTS We found that LTA rs909253 and TNF rs1800629 polymorphisms were associated with T1D in the group of Tatars. Meta-analysis of the association study results in the three ethnic groups has confirmed the association between the T1D risk and LTA rs909253 genetic variant. LTA rs909253 and TNF rs1800629 loci were also featured in combinations most significantly associated with T1D. CONCLUSION Our findings suggest that LTA rs909253 and TNF rs1800629 polymorphisms are associated with the risk of T1D both independently and in combination with polymorphic markers in other inflammatory genes, and the analysis of multi-allelic combinations provides valuable insight in the study of polygenic traits.

Abstract
Type 2 diabetes mellitus (T2DM) is one of the most acute problems of the modern world. The disease is characterized by high ratio of micro- and macrovascular complications. T2DM is a multifactorial and polygenic disease, structure of hereditary predisposition to which may be population-specific. Aim - the analysis of allelic associations of adiponectin gene (ADIPOQ, rs17366743) with T2DM, its clinical and metabolic characteristics and complications in T2DM patients resident in the Republic of Bashkortostan. MATERIAL AND METHODS 3 PCR-based method of genotyping with polymorphic marker rs17366743 of ADIPOQ gene in 433 T2DM patients and 428 healthy controls, residents of Bashkortostan. RESULTS The ratio of genotype CT and allele С was higher in T2DM patients compared with controls (15.7% vs. 6.8%; p=0.0002 and 7.8% vs. 3.4%; p<0.0001, respectively). Genotype ТТ and allele Т were less frequent in T2DM than in healthy subjects (84.3 and 93,2%; p=0.0002; 92.2 and 96.6%, p<0.0001, respectively). The association with the development of diabetic retinopathy and cataract was shown (p=0,044, p=0,008, respectively). CONCLUSIONS Allele C and genotype CT are risk markers of T2DM (OR=2.43 and 2.56 respectively).

Abstract
Recent studies have shown that chemokines play an important role in the development of chronic inflammation in adipose tissue, obesity pathogenesis, glucose intolerance and type 2 diabetes. It has also been revealed that some SNPs in chemokine genes are associated with obesity, insulin resistance, type 2 diabetes and diabetes complications in different ethnic groups. The aim of this study was to determine the associations between SNPs in chemokine genes and type 2 diabetes in participants of Tatar ethnic group, living in Bashkortostan. Case-control and cross-sectional study were included in our study design. Five SNPs were genotyped in 440 type 2 diabetes (160 men and 280 women), 58.8 ± 9.2 years old (mean ± SD), BMI 29.3 ± 3.9 kg/m2 (mean ± SD) patients of Tatar ethnicity, and a control group of 500 Tatars (180 men and 320 women), 55.2 ± 11.6 years old (mean ± SD), BMI 25.9 ± 4.3 kg/m2 (mean ± SD). The SNPs rs6749704 in CCL20 [odds ratio (OR) = 2.77 (95% CI 1.81-4.25), р = 0.0001], rs2107538 in CCL5 [odds ratio (OR) = 1.80 (95% CI 1.46-2.22), p = 0.0001] were significantly associated with type 2 diabetes. Regression analysis revealed that rs1696941 in CCL11 was associated with the onset age and duration of type 2 diabetes as well as with HbA1c level (p = 0.034, p = 0.036 and p = 0.0054, respectively). The SNPs rs223828 in CCL17 and rs6749704 in CCL20 were correlated with obesity as estimated by BMI (p = 0.0004, p = 0.029, respectively). Rs223828 in CCL17 revealed the association with postprandial glucose level (p = 0.024) and HbA1c (p = 0.008). These data demonstrate that variants of chemokine genes are associated with type 2 diabetes and obesity of Tatar ethnic group inhabiting Bashkortostan Republic. Novel associations of the polymorphic loci in CCL20 (rs6749704) and CCL5 (rs2107538) genes with type 2 diabetes had been identified as a result of the conducted research.

Abstract
Essential arterial hypertension is a disease with distinct yet unexplored inflammatory component. Our aim was to assess the role of chemokine genes and their interaction in its development. Genotyping of polymorphic markers in six chemokine genes (CXCL13, CCL8, CCL16, CCL17, CCL18, and CCL23) was performed in the group of 522 men of Tatar ethnic origin from the Republic of Bashkortostan, Russia (213 patients with essential hypertension and 309 healthy individuals without history of cardiovascular disease). We found a strong association of CXCL13 rs355689*C allele with essential hypertension under additive (OR 0.56, PFDR = 0.008) and dominant (OR 0.41, PFDR 4.38 × 10- 4) genetic model. The analysis of gene-gene interactions revealed 12 allele/genotype combinations that remained significantly associated with essential hypertension after correction for multiple testing was applied, and each of these combinations included CXCL13 rs355689 polymorphism. Our results indicate that CXCL13 rs355689 polymorphism is strongly associated with essential hypertension in the ethnic group of Tatars, alone and in combination with polymorphic markers in other chemokine genes.

Abstract
OBJECTIVE to elaborate a complex model for myocardial infarction (MI) risk assessment considering the combined effect of genetic predisposition, age and smoking. MATERIALS AND METHODS The study included two independent samples of ethnic Russians: 325 patients with MI and 185 individuals without history of cardiovascular diseases (controls) from the Moscow region, and 220 patients and 197 controls from the Republic of Bashkortostan. Genotyping of polymorphic loci of genes CRP (rs1130864), IFNG (rs2430561), TGFB1 (rs1982073), FGB (rs1800788) and PTGS1 (rs3842787) was performed. To construct the predictive models, we used logistic regression with stepwise inclusion of variables. The predictive value was evaluated by the area under the curve (AUC) in a ROC-analysis. The factor was considered as a marker at pAUC <0.05 calculated by the method of DeLong. The marker was considered effective at AUC >0.60. RESULTS Three separate genetic variants FGB rs1800788*T, TGFB1 rs1982073*TT, CRP rs1130864*TT, and biallelic combination IFNG rs2430561*A + PTGS1 rs3842787*T whose association with MI we described earlier, were used to construct the composite genetic marker (AUC=0.66 in the training and test samples) by the logistic regression method. Adding to the obtained composite genetic marker such parameters as age and smoking allowed to create a complex MI risk marker, which was characterized by the predictive value stability (AUC=0.77 in the training sample and 0.82 in the test sample). CONCLUSION The obtained complex model for MI risk assessment was reproduced in two independent samples of Russian ethnicity individuals from different regions of Russia with different gender identities, and allowed to have a reasonable chance (about 80%) of distinguishing patients and healthy individuals.

Abstract
The distribution of allele and genotype frequencies of Alu(I/D) polymorphic sites in the COL13A1 and LAMA2 genes coding extracellular matrix protein subunits was characterized in an ethnically homogeneous group (Tatars from the Republic of Bashkortostan, Russia). It was established that the frequency of individuals with the COL13A1*D/*D genotype was higher in the senile age period. The LAMA2*I/*D genotype was predisposing to longevity among women. According to the observed results, the frequency of the LAMA2*I/*D genotype was increased in senile individuals older than 90 years. The observed associations can be explained on the basis of the contemporary view by the importance of Alu elements in gene expression regulation at transcriptional and post-transcriptional levels, the involvement of collagen and laminin in maintaining the structure and function of the extracellular matrix, and the relationship between the extracellular matrix state, pathological changes and aging.

Abstract
Atherosclerosis represents an inflammatory response to the disturbance of the endothelial layer in the arterial bloodstream. In the present study, an analysis of associations of polymorphic markers for the genes controlling synthesis of proteins involved in atherosclerosis pathogenesis in coronary atherosclerosis (CA) patients (217 subjects) and in a control group (250 subjects) was conducted. The following genes were examined: rs991804 (CCL2 gene), rs1126579 (CXCR2 gene), rs4074 (CXCL1 gene), rs4073 (CXCL8 gene), rs333 (CCR5 gene), rs2471859 (CXCR4 gene), rs1801157 (CXCL12 gene), and rs2569190 (CD14 gene). Using the Monte Carlo and Markov chain (APSampler) method, allele/genotype combinations associated with both low and high CA risk were revealed. The most important findings included the following: CXCR4*T/T + CCL2*C + CCR5*I/I (P perm = 1 × 10–6, OR = 0.44, 95% CI 0.3–0.63), CXCR2*C + CD14*C + CXCL12*G + CCL2*C + CCR5*D (P perm = 4 × 10–6, OR = 5.78, 95% CI 2.34–14.28), CD14*C + CCL2*C/C + CCR5*D (P perm = 6.3 × 10–6, OR = 5.81, 95% CI 2.17–15.56), CXCL8*A + CXCR2*C + CD14*T + CXCR4*C (P perm = 0.01, OR = 3.21, 95% CI 1.63–6.31).

Abstract
The association of the variable rs1801282 locus of the PPARG2 gene (peroxisome proliferator-activated receptor gamma) with type 2 diabetes mellitus and its complications was analyzed in inhabitants of the Republic of Bashkortostan. The genotype frequencies of the variable rs1801282 locus of the PPARG2 gene did not significantly differ in groups of healthy persons and patients with type 2 diabetes in all three considered inheritance models (codominant, dominant, and recessive). At the same time, it was demonstrated that the risk of one of the diabetic complications, i.e., diabetic nephropathy, was associated with the variable rs1801282 locus of the PPARG2 gene. Diabetic nephropathy was more common in patients with the C/C genotype (62.7%) compared to the C/G and G/G genotypes (37.5%), P = 0.036. The G allele is protective in regard to diabetic nephropathy (OR = 0.36) in patients with type 2 diabetes mellitus.

Abstract
Seeking human longevity association with gene polymorphisms in transcription factors in the Tatar ethnic group, we conducted an analysis for age-related genotype, frequencies in polymorphic sites of FOXO1A (rs4943794, 72327C>G) and FOXO3A (rs3800231, 35-2764A>G) genes. Genotyping was conducted by using the PCR-RFLP approach. According to the results of logistic regression analysis, during maturity and old age periods, a decrease in the number of FOXO1A*G/*G (OR = 0.984, P = 0.004) genotype carriers occurs and an increase in the number of FOXO1A*C/*G (OR = 1.035, P = 0.014) and FOXO1A*C/*C (OR = 1.024, P = 0.033) genotype carriers occurs in the sample of subjects before gender adjustments. In the sample of long-livers, the number of FOXO1A*C/*C (OR = 0.772, P = 0.028) genotype carriers decreased among women, while the number of FOXO3A*G/*G (OR = 1.008, P = 0.0001) genotype carriers increased among both men and women. Therefore, the FOXO1A gene polymorphic site rs4943794 is associated with an acquisition of old and senescent age in a sample before gender adjustments and with women's longevity. FOXO3A gene polymorphic site rs3800231 is associated with longevity in both women and men.

Abstract
The distribution of allele and genotype frequencies of Alu(I/D)-polymorphic sites in PLAT (TPA25), PKHD1L1 (Yb8AC702), STK38L (Ya5ac2145) и TEAD1 (Ya5ac2013) genes was first characterized in the ethnically homogeneous group (Tatars from the Republic of Bashkortostan, Russia), and was established (found) the association of each gene polymorphism with age. The study group consisted of 1580 unrelated individuals aged between 21 and 109 years, including 204 long-livers. It was found that STK38L*I/D genotype had positive association with longevity in the total group (OR=1,016, p=0,034). Long-lived women had a high probability of detection of PKHD1L1*I/I (OR=1,289, p=0,009), PLAT*D/D (OR=1,175, p=0,016) and TEAD1*I/I (OR=1,047, p=0,042) genotypes. PKHD1L1*I/D genotype was a significant factor in providing of male longevity (OR=1,713, p=0,030). Therefore, age-dependent changes in genotype frequencies are specific for each studied gene.

Abstract
Aim. To perform the analysis of the association of transcription factor 7-like 2 (TCF7L2) gene rs7903146 polymorphism with type 2 diabetes mellitus (T2DM) among Tatars of Bashkortostan. Materials and methods. In this study, 169 patients with T2DM and 286 controls without clinical symptoms and laboratory signs of diabetes and without diabetes relatives were examined. Amplification of the DNA fragments was performed using real-time polymerase chain reaction (PCR) and TaqMan technique. Results. Genotype CT and allele T ratios were higher in the T2DM group than in controls (46. 7% vs. 36. 4%, p = 0. 030; 41. 7% vs. 30. 8%, p = 0. 001 respectively). There was a positive association between allele T and T2DM (OR = 1. 61), and allele C had a protective effect (OR = 0. 62, p = 0,001). Carriers of the ТТ genotype had later onset of T2DM (mean = 59. 5 years old) compared with carriers of the CT and CC genotypes (56. 1 years old, p = 0. 044). Basal C-peptide concentration, lipid levels and body mass index were not associated with TCF7L2 rs7903146 polymorphism. Conclusion. TCF7L2 rs7903146 polymorphism is associated with T2DM among Tatars of Bashkortostan.

Abstract
Hypertension is the major risk factor for stroke, and genetic factors contribute to its development. Inflammation has been hypothesized to be the key link between blood pressure elevation and stroke. We performed an analysis of the association between inflammatory mediator gene polymorphisms and the incidence of stroke in patients with essential hypertension (EH). The study group consisted of 625 individuals (296 patients with noncomplicated EH, 71 hypertensive patients with ischemic stroke, and 258 control subjects). Both patients and controls were ethnic Tatars originating from the Republic of Bashkortostan (Russian Federation). The analysis has shown that the risk of ischemic stroke was associated with the CXCR2 rs1126579 polymorphism. Our results indicate that among patients with EH, the heterozygous genotype carriers had a higher risk of stroke (OR = 1.72, 95% CI 1.01-2.92), whereas the CXCR2*C/C genotype was protective against stroke (OR = 0.32, 95% CI 0.12-0.83). As shown by the gene-gene interaction analysis, the CXCR2 rs1126579 polymorphism was also present in all genotype/allele combinations associated with the risk of stroke. Genetic patterns associated with stroke also included polymorphisms in the CCL2, CCL18, CX3CR1, CCR5, and CXCL8 (IL8) genes, although no association between these loci and stroke was detected by individual analysis.

Abstract
An association study was performed for genetic polymorphisms in ADRB3 (rs4994) and ADRA2A (rs1800544, rs553668) genes to estimate their effect on quantitative parameters, including glucose, insulin, and HOMA-IR index in women from the Tatar population of Russia. It has been shown that CT and CC are associated with metabolic syndrome and increased insulin. It was shown that ADRA2A (rs1800544) gene polymorphism was associated with high levels of insulin and an increased HOMA-IR index in GG- and GC-genotype carriers.

Abstract
Essential hypertension (EH) is a common disease with a clear genetic component. Inflammation and endothelial dysfunction play a prominent role in the development of persistent blood pressure elevation. The aim of the current study was to detect an association between EH and polymorphic markers in genes encoding for molecules involved in the control of intercellular interactions during the inflammation process. We analysed SNPs in SELE, SELP, SELL, ICAM1, VEGFA, IL1B, IL6, IL10 and IL12B genes in a group of 534 men of Tatar ethnicity (217 patients with EH and 317 controls). Using a Markov chain Monte-Carlo-based approach (APSampler), we found genotype and allelic combinations associated with EH. The most significant associations were observed for SELE rs2076059*C-SELP rs6131*A-VEGFA -2549*I-IL1B rs16944*C (p = 3.42 × 10(-5), FDR q = 0.035) and SELE rs2076059*C-SELP rs6131*A-IL12B rs3212227*C-IL1B rs16944*C (p = 323 × 10(-4), FDR q = 0.035).

Abstract
The allele and genotype frequency distribution at polymorphic loci rs3892097 (184G>A) of CYP2D6 gene, rs776746 (6986A>G) of the CYP3A5 gene and rs2740574 (-392A>G) of the CYP3A4 gene in Russians, Tatars, and Bashkirs was examined. Samples were taken from residents of Bashkortostan Republic (1240 men and women aged from 20 to 109 years and consisted of 443 Russians, 517 Tatars, and 280 Bashkirs). Allele identification was conducted using PCR-RFLP or PCR with TaqMan probes. The "nonfunctional" allele rs3892097*A of the CYP2D6 gene was detected in populations of Russians, Tatars, and Bashkirs in 17.2, 9.5, and 7.1% cases, respectively. The rs776746*G allele of the CYP3A5 gene encoding the CYP3A5 isoenzyme with decreased activity was revealed with a frequency of 94.6% in populations of Russians, 94.3% in the Tatar population, and 91.5% in the Bashkir population. The share of the minor allele rs2740574*G of the CYP3A4 was 4.0% in populations of Russians, 0.5% in the Tatar population, and 0.9% in the Bashkir population. It has been previously shown that the rs3892097*A, rs776746*G, and rs2740574*G allele frequencies vary significantly in different world populations. Since allele variants of CYP2D6, CYP3A5, and CYP3A4 genes can play essential role in interindividual and in interethnic differences in the metabolism of many therapeutic agents, the obtained results could be used in the prognosis of pharmacotherapy efficacy in populations of Russians, Tatars, and Bashkirs.

Abstract
This review is devoted to the description of research achievements in genetics of aging and longevity. It represents a certain interest for understanding of a problems of aging as a whole. There is a huge amount of results of diverse genetic studies of aging and longevity. Studies were performed with using different experimental strategies on model organisms or samples from different human populations of the world. The search for aging and longevity genes was carried out within international consortiums. The first results of whole genome sequences of super-centenarians were received. The genes influencing life expectancy were revealed in organisms of different systematic groups. Many of these genes are evolutionarily conservative. Associations between APOE, FOXO1A, FOXO3A, AKT1 gene polymorphisms and human longevity were confirmed in independent studies.

[[Length polymorphism of minisatellite repeat B2-VNTR of the bradykinin B2 receptor gene in healthy Russians and in patients with coronary heart disease]. Mol Biol (Mosk) 2014; 48:752-762.

Abstract
Bradykinin B2 receptor is involved in many processes, including the regulation of blood pressure and smooth muscle contraction, vasodilation, inflammation, edema, cell proliferation, pain. It is suggested that this receptor may be one of the factors that have cardioprotective and infarct-limiting effects. It is assumed that certain genetic variants in both coding and non-coding regions ofBDKRB2 gene may influence its expression. In the 3'-untranslated region of BDKRB2 exon 3 the minisatellite repeat B2-VNTR is located. B2-VNTR has previously been shown to affect the BDKRB2 mRNA stability. Therefore, it is important to perform the molecular genetic analysis of this minisatellite in patients with different forms of coronary heart disease in order to reveal possible associations between specific B2-VNTR alleles and certain clinical forms of coronary heart disease. In the present study, a comparative analysis of the allele and genotype frequencies of B2-VNTR was carried out in groups of healthy individuals and patients with two clinical forms of coronary heart disease (angina pectoris and myocardial infarction), ethnically Russian. The results of the B2-VNTR length polymorphism analysis indicate that this tandem repeat may be attributed to a class of low polymorphic and non-hypervariable minisatellite. In all analyzed groups we revealed three B2-VNTR alleles, consisting of 43, 38 and 33 repeat units. Alleles of 43 and 33 repeats were major in all investigated groups. No statistically significant differences were found in the B2-VNTR allele and genotype frequencies between men and women in control group, and also between healthy men and men with angina pectoris and myocardial infarction. Thus, B2-VNTR length polymorphism was not associated with these clinical forms of coronary heart disease in Russian men. However, we do not exclude the possibility of association between the B2-VNTR short alleles (38 and 33 repeats) and cardioprotective effects of bradykinin B2 receptor in women with coronary heart disease. This hypothesis requires further investigation.

Abstract
Allele and genotype frequency distributions of polymorphism rs2076059 (3832T>C) within the SELE gene rs6131 (S290N), within the SELP gene, rs1131498 (F206L), within the SELL gene, rs5498 (K469E) within the ICAM1 gene, rs35569394 (-2549(18)I/D) within the VEGFA gene, and rs1024611 (-2518A>G) within the CCL2 gene were examined in a group of patients after myocardial infarction (MI)(280 individuals) and in a control group (312 individuals). An implementation of the Markov chain and Monte-Carlo method (AP- Sampler) revealed the allele combinations associated with decreased and increased risk of MI. Among these the most important allele combinations were SELE*C + SELP*S + CCL2*A (FDR = 0.0005; OR = 0.42) SELP*S + CCL2*A (FDR = 0.0009; OR= 0.36}, SELL*F + VEGFA*I+ CCL2*G/G(FDR = 0.0009; OR = 4.17) VEGFA*I+ CCL2*G/G (FDR = 0.0009; OR = 3.76), SELE*C + CCL2*A (FDR = 0.0023; OR = 0.47), and SELL*I+ CCL2*G/G (FDR = 0.003; OR = 3.15).

Abstract
On a sample of 1240 persons from Bashkortostan, including Russian, Bashkirs and Tatars, the analysis of allele and genotype frequencies distribution of CYP1A2 gene polymorphism -163C>A was performed by PCR-RFLP in view of belonging to a particular age cohort. In Russian and Bashkirs ethnic groups we observed age-dependent decrease of CYP1A2*C allele and CYP1A2*CI*C genotype frequencies (in Russian statistically significant for allele and genotype, the Bashkirs--only for allele) and a statistically significant increase of CYP1A2*A allele and CYP1A2*A/*A genotype frequencies. The set reduction in the frequency of the wild allele CYP1A2*C and increasing the frequency of the mutant allele CYP1A2*A with age may be due to greater survival of persons who are carriers of that allelic variants of CYP1A2 gene, providing a more efficient metabolism of xenobiotics.

Abstract
We performed the analysis of genotype frequency dynamics of CASP8, BCL2 and BAX genes polymorphic markers between 21 and 109 years in the group of Ethnic Tatars from Bashkortostan. Genotyping was carried out using PCR and PCR-RFLP. We found associations between age and -652(6N)I/D polymorphism of CASP8 gene (rs3834129), 140016C>T polymorphism of BCL2 gene (rs12454712) and 919A>G polymorphism of BAX gene (rs1805419). An increase of genotype frequency of BCL2*C/*C and decrease of genotype frequency of CASP8*I/*D was observed in male of senile age; and also decrease of genotype frequency of BAX*G/*G among long-livers. In female of longevity age, the number of CASP8*I/*D, BCL2*T/*T and BAX*A/*A genotype carriers was higher and number of CASP8*DI/*D, BCL2*C/*C, BAX*A/*G and BAX *G/*G genotype carriers was reduced.

Chemokine CCL2, or monocytic chemoatractant protein 1 (CCL2/MCP-1) plays an important role in the development of cardiovascular diseases. In the present study, genotypes of four polymorphic markers (rs1860190, rs1024611, rs3917887, and rs991804) of the CCL2gene were identified in the population of Tatars (residents of the Republic of Bashkortostan). Analysis of associations of these markers with essential hypertension (EH) was carried out. It was demonstrated that haplotype CCL2*A*G*D*T was associated with the increased risk of EH (P = 0.01; OR = 1.53).

Abstract
TP53 and NFKB1 genes represent considerable interest as candidate genes of human aging and longevity. The allele and genotype frequency distributions of TP53 R72P (rs1042522) polymorphism and NFKB1 2592 + 58T > A (rs4648110) polymorphism were characterized in groups of men and women of 21-109 years in the given research. No statistically significant distinctions in allele and genotype frequencies between long-livers, old people and other age groups were revealed. On the basis of logistic regression analysis results it is obviously possible to make the conclusion that polymorphism R72P of TP53 gene and polymorphism 2592 + 58T > A of NFKB1 genes is associated with the age mainly throughout elderly and senile ranges of years. Relative chances to achieve the age of 80-90 years are higher in carriers of TP53*R/*R and NFKB1*A/*A genotypes. It is also possible to believe that TP53 and NFKB1 genes are frailty genes, instead of longevity ones.

Abstract
The research was aimed at studying molecular genetics basis of human longevity. The genotyping of polymorphisms in genes of interleukin 6 (IL-6, 7p21, -572G>C, rs1800796), 10 (IL-10, 1q31-q32, -627C>A, rs1800792), 12, (IL-12B, 5q31.1-q33.1, -1159C>A) and tumor necrosis factor-alpha (TNF-alpha, 6p21.3, -308G>A, rs1800629) from ethnically homogeneous population (Tatars from Bashkortostan Republic) has been carried out. Distributions of allele and genotypes frequencies in different age groups including old men and long-livers have been characterized. Associations have been revealed between age and -627C>A polymorphism of IL-10 gene in men, -572G>C polymorphism of IL-6 gene and -308G>A polymorphism of TNF-alpha gene in women. As a whole the data obtained by us confirm the assumption that polymorphism of cytokine genes can influence on human lifespan.

Abstract
M129V polymorphism of prion protein gene PRNP has been studied in patients with multiple sclerosis (MS) and healthy ethnic Russians from Bashkortostan using allele-specific PCR. The genotype frequency distribution of the examined polymorphism in Russians from Bashkortostan was similar to that in European populations. MM, MV, and VV genotype frequencies in control group and in the MS patients were 50.24%, 42.58%, 7.18% and 43.33%, 45.83%, 10.84%, respectively. It was shown that in the group of MS patients with onset of the disease at the age of 21 and older, the frequency of the VV genotype was higher than in the control group (14.3% versus 6.18%, respectively, P = 0.041). We suggest that the VV genotype is associated with higher risk factor of MS development in the patients aged 21 years and older.

Abstract
The multiple sclerosis is a complex disease of the central nervous system with the pronounced hereditary predisposition. The purpose of our research consisted in acknowledgement of the assumption on importance of apolipoprotein E gene (APOE) polymorphism in exon 4 in development of the multiple sclerosis in ethnic Russians. Research was lead on the samples independently collected in Moscow (106 patients and 189 persons of control group), Sverdlovsk area (54 and 109, accordingly) and republic Bashkortostan (119 and 285, accordingly). 2059C/T and 2197C/T polymorphisms of APOE gene, which determine aminoacid substitutions C112R and R158C in apolipoprotein E, were determined by polymerase chain reaction with the following restriction analysis of amplicons. There was not detected statistically significant distinctions on genotypes frequencies and alleles frequencies between control group and group of patients with multiple sclerosis. APOE*4 allele is not assosiated with risk of development of the multiple sclerosis at ethnic Russians.

Abstract
Multiple sclerosis (MS) is a multifactorial disease of the central nervous system. The apolipoprotein E (APOE) and interleukin 1 beta (IL1B) genes are considered to be candidate genes of MS. The aim of the study was to examine the hypothesis of the importance of APOE and IL1B gene polymorphisms in MS development in ethnic Tatars. DNA samples isolated by phenol-chloroform extraction from peripheral blood of 383 ethnic Tatars (120 MS patients and 263 healthy donors) were studied. 112C/R and 158R/C APOE gene polymorphisms as well as -511T/C IL1B gene polymorphism were analyzed by polymerase chain reaction (PCR) followed by PCR product digestion by endonuclease. Odds ratio (OR) values were used for evaluation of the relative risk of alleles and(or) genotype combinations. It has been shown that APOE*2/*3 genotype is associated with low risk of the disease development (OR = 0.20) in women. A combined effect of APOE and IL1B allelic variants has been discovered indicating the increased risk of the disease development in the carriers of APOE*4 and IL1B*T/*T alleles (OR = 4.76).

Abstract
Comparison in genotype and allele frequencies of people groups of younger (from 1 till 20 years), middle (21-55 years), elderly (56-74 years), senile (75-89 years) age and long-livers (90-109 years) have been performed (only 1116 person) with the purpose of analysis of molecular-genetic bases of ageing and longevity of the person. Allele variants of PON1 gene have been identified by polymerase chain reaction in a combination with restriction analysis. In the general sample of Tatars genotypes PON1*Q/*Q, PON1*Q/*R and PON1*R/*R are revealed with frequencies of 46.15, 44.35 and 9.5%, alleles PON1*Q and PON1*R are found with frequencies of 68.32 and 31.68% accordingly. Statistically significant distinctions on frequencies of genotypes and alleles between separate age groups are found. It has appeared, that frequency of PON1*R allele (28.46%) is lowered among old men in comparison with those among persons of younger age (37.42%, P = 0.009). However essentially above in group of long-livers, than in group of old men, frequencies allele PON1*R (P = 0.005) and genotype PON1*R/*R (P = 0.01).

Abstract
Polymerase chain reaction was used to study the association of polymorphic markers I/D of the angiotensin-converting enzyme gene (ACE) and A1166C of the angiotensin II type 1 receptor gene (AT2R1) with chronic heart failure (CHF) in Russian and Tatar patients that had had myocardial infarction. In Russian patients aged 50 years or younger that had had macrofocal myocardial infarction, the CC genotype of the A1166C polymorphic marker of gene AT2R1 was associated with an increased risk of CHF (OR = 11.36). Genotype DD and allele D of the I/D polymorphic marker of gene ACE were associated with a more severe CHF (functional class III-IV) in Russian patients (OR = 3.50 and 2.06). In Tatar patients, polymorphic markers I/D of gene ACE and A1166C of gene AT2R1 were not associated with CHF.

Abstract
The EcoR1 polymorphism of the apolipoprotein B gene (APOB) is thought to be associated with atherothrombotic type of ischemic stroke (ATTIS) with the APOB*R1/R2 genotype as a marker of increased risk for ATTIS. We estimated odds ratio for this genotype as 2.17 in ethnic Russians and 3.39 in ethnic Tartars. The association between the EcoR1 APOB gene polymorphism and ATTIS confirmed the results of previous studies on relation of the APOB gene to vascular pathology caused by elevated lipid level and atherogenesis.

Abstract
The method of polymerase chain reaction was used to analyze T174M polymorphism at the angiotensinogen (AGT) gene in a number of populations of the Volga-Ural region, belonging to Finno-Ugric (Komi-Permyaks, Maris, Mordovians, and Udmurts), Turkic (Chuvashes, Tatars, and Bashkirs), and Eastern-Slavic (Russians) ethnic groups. Population-specific patterns of the polymorphic alleles and genotypes frequency distribution were established. Comparison of the results with the literature data on the AGT gene polymorphism in different world populations provided identification of specific trends in the changes of genotype frequency of the AGT gene depending on the ethnicity of the populations.

Abstract
Population-genetic study of indigenous populations representing three ethnic Chuvash group: highland (Cheboksarsk and Morgaush district), lowland (Kanash district) and mid-lowland (Marposad district). Eight polymorphic DNA loci of the nuclear genome (VNTR/PAH, STR/PAH, VNTR/ApoB, VNTR/DAT1, APF, VNTR/eNOS, IVS6aGATT, and KM.19/PstI) were examined in the population of each district. For each of the four population, we estimated the allele and genotype frequency distributions at each polymorphic system, heterozygosities HS and between-population differences FST. In the combined Chuvash sample, HS = 0.464 and FST = 0.006. Loci VNTR(DAT) and VNTR(ApoB) showed highest between-population differentiation (0.009 < or = FST < or = 0.012), and loci IVS6aGATT, APF, VNTR/eNOS, and D7S23 (KM.19), lowest differentiation (0.001 < or = FST < or = 0.003). Analysis of genetic distances revealed somewhat higher genetic similarity between the Cheboksarsk and Morgaush populations belonging to the highland Chuvash group, whereas the highland Chuvash population from the Marposad district, which belong to the mid-lowland group, was more distant from the former populations.

Abstract
The apolipoprotein E (ApoE) gene polymorphism resulting from nucleotide substitutions in exon 4 was analyzed in Russian and Tatar patients with myocardial infarction (MI) from Bashkortostan. Alleles epsilon 2, epsilon 3, and epsilon 4 were identified by PCR. The genotype frequency distribution proved to be age-dependent in healthy Russians, genotype E2/3 increasing in frequency in subjects beyond 45. Russians who suffered MI under 45 had lower frequencies of genotype E3/3 (50.00% vs. 75.47% in controls of the same age, P = 0.013, OR = 0.33) and allele epsilon 3 (72.12% vs. 85.85%, P = 0.020, OR = 0.43) and a higher frequency of allele epsilon 4 (22.12% vs. 10.38%, P = 0.030, OR = 2.45). Russians who suffered MI complicated by cardiogenic shock (CS) had a significantly higher frequency of genotype E3/4 and lower frequencies of genotype E3/3 and allele epsilon 3 as compared with MI patients without CS. In Tatars, genotype E4/4 occurred at a frequency of 14.29% in patients who suffered MI under 45, and was not detected in healthy subjects of the same age (P = 0.024, OR = 17.85). Thus, the ApoE polymorphism was associated with higher risk of MI in Russians and Tatars under 45.

Abstract
The alleles and genotypes of the T174M polymorphism of the angiotensinogen gene were PCR-analyzed in Russians and Tatars from Bashkortostan. The genotype frequency distribution observed in either ethnic group did not differ from that reported for other populations. The T174M polymorphism was tested for association with essential hypertension (EH). Genotypes TT, TM, and MM were found respectively in 82.56, 13.95, and 3.49% normotensive Russians and in 83.81, 16.19, and 0% normotensive Tatars. The frequency of genotype TM in patients with EH onset beyond 45 years of age was significantly higher than in controls of the same age without signs of cardiovascular disorders (51.72 vs. 11.11% in Russians and 45.45 vs. 16% in Tatars). Patients with EH onset under 45 did not differ in genotype frequency distribution from normotensive subjects of the same age. Genotype TM was associated with higher risk of EH in people aged beyond 45.

Abstract
The purpose of this study was to determine whether HindIII restriction polymorphism found in intron 8 of lipoprotein lipase gene is associated with the onset of myocardial infarction (MI) in Russians and Tartars living in Bashkortostan. HindIII polymorphism was investigated by the polymerase chain reaction in myocardial infarction survivors (males aged under 55 years (98 Russians and 68 Tartars) and in controls (53 Russians and 80 Tartars). The distribution of genotypes and allele frequencies in the controls were as follows: the frequencies of genotypes HindIII(-/-), HindIII(+/-), and HindIII(+/+) in Russians (3.77, 49.06, and 47.17%, respectively) did not differ from those in Tartars (7.50, 51.24, and 41.25%, respectively), while the frequency of HindIII(-) allele was 28.30% in Russians and 33.13% in Tartars. Among Tartars, the HindIII(+/+) genotype was more common in myocardial infarction survivors than in controls (OR 2.03). In the Russians this genotype was not associated with the risk of MI. The frequencies of HindIII(+/+) genotype and allele HindIII(+) were significantly higher (OR 8.96 and 6.71, respectively) and frequencies of HindIII(+/-) genotype and allele HindIII(-) were lower (OR 0.13 and 0.15) in Russian patients with repeated MI. These findings indicate that HindIII polymorphism may be a genetic risk factor for MI before 55 years of age in the Tartars and for repeated MI in Russians. This association prompts genotyping of HindIII polymorphism for predicting MI recurrence in Russian survivors after MI.

Abstract
The 27-bp tandem repeat polymorphism in intron 4 of the endothelial nitric oxide synthase gene (eNOS) in populations of the Volga-Ural region was studied by means of polymerase chain reaction. In Russians and Tatars, the possible association of this polymorphism with coronary heart disease complicated by either myocaridal infarction or by essential hypertension was examined. Russians with essential hypertension associated with hypertrophy of the left ventricle displayed a statistically significant increase of the eNOS4A/B genotype and the A allele frequencies along with the decrease of the frequencies of the eNOS4B/B genotype and the B allele. In Tatars survived from myocardial infarction and with the risk of cardiovascular diseases (smoking or burdened heredity), a statistically significant increase of the frequencies of the eNOS4A/B genotype and the A allele was observed. Thus, in Russians the eNOS4A/B genotype was associated with the development of essential hypertension, while in Tatars it was associated with the risk of myocardial infarction.

Abstract
Nei's coefficient of genetic differentiation (Gst) was used to estimate the intergroup differentiation of four ethnic geographic groups of Bashkirs and the interethnic differentiation of seven ethnoses (Bashkirs, Tatars, Chuvashes, Udmurts, Maris, Komis, and Mordovians) from the Volga-Ural region. The coefficient of genetic differentiation calculated from data on four polymorphic loci (MET, D7S23, PKU, and apoB) and classical biochemical markers (AB0, MN, Rh, Hp, and AcP) of the nuclear genome was similar in all tested populations. The genetic difference between the ethnoses from the Volga-Ural region (Gst = 1.91%) was intermediate between that in European (Gst = 1.18%) and Siberian (Gst = 5.84%) ethnoses.
