Mol Cell Probes 2024; 75:101960. [PMID: 38583643 DOI: 10.1016/j.mcp.2024.101960] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 03/12/2024] [Accepted: 04/01/2024] [Indexed: 04/09/2024]
Abstract
Variable Fragment Length Allele-Specific Polymerase Chain Reaction (VFLASP) and Amplification Refractory Mutation System (ARMS) are reliable methods for detecting allelic variations resulting from single base changes within the genome. Due to their widespread application, allele variations caused by Single Nucleotide Polymorphisms (SNPs) can be readily detected using allele-specific primers. In the context of the current study, VFLASP was combined with ARMS method as a novel strategy to enhance the efficacy of both techniques. Clinically important base variations within SNP regions used in the study were detected by a fragment analysis method. To validate the accuracy of the developed VFLASP-ARMS method, specifically designed synthetic sequences were tested using a capillary electrophoresis system. Allele-specific primers exhibit differences solely at the 3' end based on the sequence of the SNP. Additionally, to increase the specificity of the primers, a base was intentionally added for incompatibility. Therefore, allele discrimination on fragment analysis has been made possible through the 3-6 bp differences in the amplicons. With the optimization of the system, designed synthetic sequences provided reliable and reproducible results in wild-type, heterozygous, and homozygous genotypes using the VFLASP-ARMS method. Hence, our results demonstrated that VFLASP-ARMS method, offers a novel design methodology that can be included in the content of SNP genotyping assays.

Ozuynuk-Ertugrul AS, Kirsan CB, Erkan AF, Ekici B, Komurcu-Bayrak E, Coban N. Genetic variants of ANRIL and coronary artery disease: Insights from a Turkish study population. Gene 2024; 917:148475. [PMID: 38631653 DOI: 10.1016/j.gene.2024.148475] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 03/27/2024] [Accepted: 04/15/2024] [Indexed: 04/19/2024]
Abstract
BACKGROUND AND AIM Coronary artery disease (CAD) remains a leading cause of morbidity and mortality globally despite advancements in treatment. Long non-coding RNAs (lncRNAs) play crucial roles in the atherosclerotic process, with ANRIL being one such lncRNA. This study explored the association between ANRIL polymorphisms (rs1333049:C > G, rs564398:T > C, and rs10757274:A > G) and CAD along with CAD risk factors in a Turkish patient group. METHODS The study included 1285 participants, consisting of 736 patients diagnosed with CAD (mean age = 63.3 ± 10.5 years) and 549 non-CAD controls (mean age = 57.52 ± 11.01 years). Genotypes for rs1333049, rs564398, and rs10757274 were determined using qRT-PCR. RESULTS G allele carriage of both rs1333049 and rs10757274 polymorphisms were associated with higher Gensini score, SYNTAX score, total cholesterol, and triglyceride levels in female CAD patients and non-CAD males. Females with rs564398 CC genotype were more susceptible to CAD (p = 0.02) and severe CAD (p = 0.05). Moreover, the G and T alleles of rs10757274 and rs564398 were more prevalent among hypertensive males. Also, carrying the C allele for rs564398 was associated with a decreased risk for type 2 diabetes mellitus (T2DM) (p = 0.02). Besides, carriers of the rs1333049 C allele for decreased risk for T2DM (p = 0.03) and CAD complexed with T2DM (p = 0.04) in logistic regression analyses. CONCLUSIONS In conclusion, selected ANRIL polymorphisms were associated with CAD presence/severity and CAD risk factors, T2DM, and hypertension. Notably, this study, the largest sample-sized study examining the effects of selected polymorphisms on CAD and its risk factors among Turkish individuals, supported the findings of previous studies conducted on different ethnicities.

9p21 Locus Polymorphism Is A Strong Predictor of Metabolic Syndrome and Cardiometabolic Risk Phenotypes Regardless of Coronary Heart Disease. Genes (Basel) 2022; 13:genes13122226. [PMID: 36553493 PMCID: PMC9778176 DOI: 10.3390/genes13122226] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Revised: 11/20/2022] [Accepted: 11/23/2022] [Indexed: 11/29/2022] Open
Abstract
The world population is genetically predisposed to metabolic syndrome (MetS) and its components, also known as cardiometabolic risk phenotypes, which can cause severe health complications including coronary heart disease (CHD). Genetic variants in the 9p21 locus have been associated with CHD in a number of populations including Pakistan. However, the role of the 9p21 locus in MetS and cardiometabolic risk phenotypes (such as obesity, hypertension, hyperglycemia, and dyslipidemia) in populations with CHD or no established CHD has not been explored. Therefore, the present study was designed to explore the association of the minor/risk allele (C) of 9p21 locus SNP rs1333049 with MetS or its risk phenotypes regardless of an established CHD, in Pakistani subjects. Genotyping of rs1333049 (G/C) was performed on subjects under a case-control study design; healthy controls and cases, MetS with CHD (MetS-CHD+) and MetS with no CHD (MetS-CHD-), respectively. Genotype and allele frequencies were calculated in all study groups. Anthropometric and clinical variables (Means ± SD) were compared among study groups (i.e., controls, MetS + CHD and MetS-CHD) and minor/risk C allele carriers (GC + CC) vs. non-carriers (Normal GG genotype). Associations of the risk allele of rs1333049 SNP with disease and individual metabolic risk components were explored using adjusted multivariate logistic regression models (OR at 95% CI) with a threshold p-value of ≤0.05. Our results have shown that the minor allele frequency (MAF) was significantly high in the MAF cases (combined = 0.63, MetS-CHD+ = 0.57 and MetS-CHD- = 0.57) compared with controls (MAF = 0.39). The rs1333049 SNP significantly increased the risk of MetS, irrespective of CHD (MetS-CHD+ OR = 2.36, p < 0.05 and MetS-CHD- OR = 4.04, p < 0.05), and cardiometabolic risk phenotypes; general obesity, central obesity, hypertension, and dyslipidemia (OR = 1.56-3.25, p < 0.05) except hyperglycemia, which lacked any significant association (OR = 0.19, p = 0.29) in the present study group. The 9p21 genetic locus/rs1333049 SNP is strongly associated with, and can be a genetic predictor of, MetS and cardiometabolic risks, irrespective of cardiovascular diseases in the Pakistani population.

Abstract
We conducted this meta-analysis to estimate associations between CDKN2B antisense (CDKN2B-AS) rs2383207 polymorphism and susceptibility to atherosclerosis. A systematic literature research of Google Scholar and PubMed was performed to identify eligible studies. Overall, eight studies were included for meta-analyses. The association was assessed by statistical odds' ratio (OR) with 95% confidence interval (CI). RevMan software (Cochrane Collaboration, 5.3. Copenhagen) was used for the meta-analysis. Pooled overall analyses showed that rs2383207 polymorphism was associated with the risk of atherosclerosis in the whole population. Additional analyses by ethnicity revealed that rs2383207 polymorphism was associated with susceptibility to atherosclerosis in Asians and Caucasians. Our results suggest that rs2383207, might serve as genetic biomarkers of atherosclerosis. Further, studies will be required to confirm the observed association.

Abstract
BACKGROUND Coronary artery disease (CAD) and aortic aneurysms (AA) are two cardiovascular diseases that share a multifactorial aetiology. The influence of family history and genetics on the two diseases separately and in association is well known, but poorly elucidated. This comprehensive review aims to examine the current literature on the gene ANRIL (antisense non-coding RNA in the INK4 locus) and its associations with CAD and AA. METHODS A database search on OVID, PubMed and Cochrane to identify articles concerning single nucleotide polymorphisms (SNPs) associated with ANRIL and their respective incidences of, and impact on, CAD and AA across populations. RESULTS Cohort studies across various ethnicities reveal that various ANRIL SNPs are significantly associated separately with CAD (rs1333040, rs1333049 and rs2383207) and AA (rs564398, rs10757278 and rs1333049), and that these SNPs are present in significant proportions of the population. SNP rs1333049 is significantly associated with both diseases, but is positively correlated with AAA and negatively correlated with CAD. This review further outlines several pathophysiological links via endothelial and adventitial cells, vascular smooth muscle cells and sense gene interaction, which may explain these genetic associations identified. CONCLUSION Given the associations uncovered between ANRIL polymorphisms and CAD and AA, as well as the molecular mechanisms which may explain the underlying pathophysiology, ANRIL appears to be strongly linked with both diseases. ANRIL may hence have a future application in screening normal patients and risk stratifying patients with both diseases. Its role in linking the two diseases is yet unclear, warranting further studies.

Abstract
Background Primary open-angle glaucoma (POAG) is affected by both genetics and environmental factors. CDKN2B-AS1 polymorphisms have been reported to be involved in the pathogenesis of POAG. However, the results of the genetic associations between the CDKN2B-AS1 polymorphisms and POAG risk were inconclusive. Aims This study aimed to evaluate the correlation of CDKN2B-AS1 polymorphisms and POAG susceptibility using a meta-analysis. Methods Meta-analysis was performed by searching PubMed, Web of science, the Cochrane database of system reviews, CNKI, and Embase databases. The relationship of CDKN2B-AS1 rs4977756, rs10120688, rs2157719, and rs7049105 polymorphisms and POAG risk was evaluated by the odds ratios (ORs) and 95% confidence intervals (CIs). Results Eleven studies with 8290 cases and 13,485 controls were included in the present meta-analysis. The alleles of rs4977756 and rs10120688 significantly increased the risk of POAG (rs4977756: OR = 1.20, 95%CI = 1.03–1.39, p = 0.02; rs10120688: OR = 1.36, 95%CI = 1.29–1.44, p < 0.00001). As for ethnicity, rs4977756 polymorphism significantly increased POAG risk in Caucasians (OR = 1.33, 95%CI = 1.12–1.57, p = 0.0009), but not in Asians. In addition, the rs2157719 allele was significantly associated with POAG risk in Asians (OR = 0.66, 95%CI = 0.55–0.80, p < 0.0001), but not in Caucasians (p > 0.05). Conclusions The CDKN2B-AS1 rs4977756 might increase the POAG risk in Caucasian population, and rs2157719 might decrease the POAG risk in Asian population, while rs10120688 might increase the risk of POAG.

Abstract
Purpose Coronary artery disease (CAD) is one of the most important leading causes of morbidity and mortality worldwide. Few studies have been carried out in the Saudi population regarding the association of rs10757278 polymorphism with CAD. This study aimed to investigate the association of the rs10757278 polymorphism with CAD in Saudi population. Materials and Methods In this case-control study, we recruited 437 patients with CAD and 251 cross-matched healthy controls and performed polymorphism genotyping for rs10757278 using a polymerase chain reaction followed by a restriction fragment length polymorphism analysis. Results The G allele (OR-1.44; 95% CI: 1.15–1.80; p=0.001), as GG (OR-2.13; 95% CI: 1.35–3.36; p=0.0009), in the dominant (OR-1.47; 95% CI: 1.03–2.10; p=0.03) and recessive mode (OR-1.84; 95% CI: 1.26–2.70; p=0.001) of inheritance showed a high-risk association. A disease stratified risk analysis was conducted and comparisons were made using an ANOVA analysis. Diabetes showed a risk association (p=0.001). However, a regression analysis confirmed that for the CAD cases, there was an association between the GG genotype and diabetes (p=0.005). Conclusion The results of this study suggest that the polymorphism rs10757278 is related to a high risk of CAD in a Saudi population.

Abstract
The relationship between Cyclin-Dependent Kinase Inhibitors 2B Antisense RNA 1 (CDKN2B-AS1) variants rs1333049 G/C and rs4977574 A/G and the risk of coronary heart disease is unclear. We conducted an update analysis incorporating odds ratios and 95% confidence intervals to assess the correlation. Furthermore, we used in silico analysis to investigate the genes and proteins that interact with CDKN2B. Fifty case-control studies with a sample size of 35,915 cases and 48,873 controls were involved. We revealed that the rs1333049 C allele could increase the risk of coronary heart disease in the overall analysis (allele comparison, OR = 1.13, 95%CI = 1.05–1.21, P = 0.001; homozygous contrast, OR = 1.29, 95%CI = 1.11–1.49, P = 0.001; dominant comparison, OR = 1.14, 95%CI = 1.03–1.27, P = 0.011; recessive comparison, OR = 1.21, 95%CI = 1.10–1.34, P < 0.001). In subgroup analysis, positive correlations were detected in studies involving West and East Asians and in population-based control studies. The rs4977574 G allele was also a risk factor for coronary heart disease (allelic comparison, P = 0.001; heterozygous comparison, P = 0.003; homozygous comparison, P < 0.001; dominant comparison, P = 0.001). These results indicate correlation of CDKN2B-AS1 rs1333049 G/C and rs4977574 A/G variants may be correlated with the risk of coronary heart disease.

Abstract
Background Coronary arteries disease (CAD) has been recognized as one of the most common causes of death worldwide, with an estimated seven million deaths annually. Methods Two hundred blood samples from Iranian CAD patients and normal healthy controls were collected. CAD and the 9p21 locus variants rs1333049 and rs10757278 were analyzed for potential associations. Results No significant differences in rs10757278 and rs1333049 polymorphisms were found between patients and controls, but a significant relationship was found between rs10757278 and rs1333049 in CAD patients at the genotype level (p= 0.0323). At the haplotype level and on the basis of diplotype analysis, a significant relationship was found between patients and controls (OR= 5.16, p= 0.047, 95% CI: 1.02-26.0). In CAD patients, rs10757278 and rs1333049 were associated at locus 9p21. Conclusion The inconsistency between the results of this and other studies on different CAD populations may be due to high population, different ethnicities, low prevalence of some alleles in populations, and interactions of different genes.

Abstract
Background Coronary heart disease (CHD) is one of the most severe cardiovascular diseases. Cyclin‐dependent kinase inhibitor 2B antisense RNA 1 (CDKN2B‐AS1) is a significant susceptibility locus for cardiovascular disease by regulating inflammation response and cell cycle. The aim of this study was to assess whether CDKN2B‐AS1 polymorphisms are associated with CHD risk in the Chinese Han population. Methods A total of 501 CHD patients and 496 healthy controls were recruited from Central South University Xiangya School of Medicine Affiliated Haikou Hospital, five CDKN2B‐AS1 polymorphisms (rs10115049, rs75227345, rs2383205, rs10738606, and rs1333049) were analyzed by the Agena MassARRAY platform. The association of CDKN2B‐AS1 polymorphisms and CHD risk was determined by odd ratios (OR) and 95% confidence intervals (CI) using logistic regression. Results CDKN2B‐AS1 rs10738606 was significantly associated with CHD under codominant (p = .03), dominant (p = .019), recessive (p = .010), additive (p = .003), and allele (p = .003) models. Gender‐based subgroup tests showed that four polymorphisms (rs75227345, rs2383205, rs10738606 and rs1333049) were associated with CHD in males (p < .05). And age‐based subgroup tests indicated that rs2383205 and rs10738606 were associated with CHD among individuals, respectively (p < .05). For CHD patients, rs1333049 decreased the risk of diabetes under heterozygote (p = .014) and dominant (p = .024) models. Conclusions In conclusion, CDKN2B‐AS1 polymorphisms were associated with CHD risk in the combined or subgroup tests, suggesting an important role of CDKN2B‐AS1 in CHD susceptibility.

CDKN2B gene expression is affected by 9p21.3 rs10757278 in CAD patients, six months after the MI. Clin Biochem 2019; 73:70-76.

Abstract
BACKGROUND Chromosomal region 9p21.3 is most robustly associated with coronary artery disease (CAD) in western European populations. However, heterogeneity in CAD phenotypes leads to uncertainty whether 9p21.3 is associated with stable and/or acute clinical presentations of CAD. 9p21.3 is rich in regulatory elements, but the underlying mechanisms of its actions in CAD remain unclear. We investigate the association of 9p21.3 two haplotype blocks lead variants (rs10757278 and rs518394) with first-ever non-fatal myocardial infarction (MI) in CAD patients and their association with CDKN2B mRNA expression in peripheral blood mononuclear cells 6 months after the event. METHODS We included CAD patients with sustained first MI (n = 523) and controls (n = 583). Gene expression was assessed in 72 patients 6 months after MI and 43 healthy controls. TaqMan® technology was used for the gene expression and genotyping analysis. RESULTS CDKN2B mRNA was significantly lower in MI patients compared with the controls (p = 0.002) and in patients carrying the rs10757278 G risk allele versus AA homozygotes (p = 0.012) 6 months after the event. While we confirmed the association of rs10757278 with CDKN2B expression in MI patients, we failed to find an association between the investigated variants and MI or disease burden. CONCLUSIONS We suggest a dysregulation of gene expression in the 9p21.3 region six months after acute MI, which is affected by a genetic variant in patients. The rs10757278 rare allele is one factor that might lead to prolonged risk for proatherogenic complications.

J Diabetes Investig 2018; 9:1189-1195. [PMID: 29356453 PMCID: PMC6123029 DOI: 10.1111/jdi.12804] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2017] [Revised: 01/09/2018] [Accepted: 01/10/2018] [Indexed: 01/06/2023] Open
Abstract
AIMS/INTRODUCTION Variants on chromosome 1p13 have been associated with coronary artery disease and acute myocardial infarction risk in different ethnic groups. The present study aimed to investigate the association between 1p13 polymorphisms and the development of peripheral artery disease (PAD) in a Chinese population with type 2 diabetes mellitus. MATERIALS AND METHODS 1p13 polymorphisms, rs599839, rs646776 and rs12740374, were assessed in a cohort of 882 type 2 diabetes mellitus patients including 440 type 2 diabetes mellitus patients with PAD (DM + PAD group) and 442 patients without PAD (DM group). Genotyping was carried out using TaqMan assay. RESULTS Compared with the DM group, the frequencies of the minor G allele of both rs599839 and rs646776 and the minor T allele of rs12740374 decreased (P = 0.013, P = 0.019 and P = 0.005, respectively), and the frequencies of rs599839 AG + GG, rs646776 AG + GG and rs12740374 CT+TT genotypes were statistically significantly decreased as well (P = 0.017, P = 0.011 and P = 0.007, respectively) in the dominant model in the DM + PAD group than in the DM group. Multivariate unconditional logistic regression analyses adjusted for age, glycated hemoglobin, triglyceride, low-density lipoprotein cholesterol, smoking, hypertension, diabetes duration, coronary heart disease and cerebral infarction showed that the genotypic distribution of rs599839 AG + GG, rs646776 AG + GG and rs12740374 CT + TT remained statistically different between the DM and DM + PAD group (P = 0.014, P = 0.003 and P = 0.004, respectively). The frequencies of haplotype GGT were statistically significantly different between groups (P = 0.08). CONCLUSIONS The present study strongly supports that genotypes of rs599839, rs646776 and rs12740374 on 1p13 are protective factors for diabetic PAD in a Chinese population. Haplotype GGT generated by rs599839, rs646776 and rs12740374 might also decrease the risk of the disease.

Abstract
Coronary artery disease (CAD) has a complex etiology involving numerous environmental and genetic factors of disease risk. To date, the genetic 9p21 locus represents the most robust genetic finding for prevalent and incident CAD. However, limited information is available on the genetic background of the severity and distribution of CAD. CAD manifests itself as stable CAD or acute coronary syndrome. The Gensini score quantifies the extent CAD but requires coronary angiography. Here, we aimed to identify novel genetic variants associated with Gensini score severity and distribution of CAD. A two-stage approach including a discovery and a replication stage was used to assess genetic variants. In the discovery phase, a meta-analysis of genome-wide association data of 4,930 CAD-subjects assessed by the Gensini score was performed. Selected single nucleotide polymorphisms (SNPs) were replicated in 2,283 CAD-subjects by de novo genotyping. We identified genetic loci located on chromosome 2 and 9 to be associated with Gensini score severity and distribution of CAD in the discovery stage. Although the loci on chromosome 2 could not be replicated in the second stage, the known CAD-locus on chromosome 9p21, represented by rs133349, was identified and, thus, was confirmed as risk locus for CAD severity.

Abstract
OBJECTIVE Investigate the association of rs17465637 gene MIAF3 (1q41), rs1376251 gene TAS2R50 (12p13), rs4804611 gene ZNF627 (19p13), rs619203 gene ROS1 (6q22), rs1333049 (9p21), rs10757278 (9p21), rs2549513 (16q23), rs499818 (6p24) associated with myocardial infarction available from the international genome-wide studies with sudden cardiac death (SCD) in a case-control study. METHODS A sample of SCD cases (n=285) was formed using the WHO criteria; the control sample (n=421) was selected according to sex and age. DNA was isolated by phenol-chloroform extraction from the myocardial tissue of SCD cases and blood of control cases. The groups were genotyped for the selected SNPs by real-time PCR using TaqMan probes (Applied Biosystems, United States). RESULTS No statistically significant differences in the genotype and allelic frequencies of studied single nucleotide polymorphisms between sudden cardiac death cases and control were detectable in general group. By separating the groups of sex and age differences in the genotype frequencies of rs1333049, rs10757278 and rs499818 are statistical significance. Genotypes CC of rs1333049 and GG of rs10757278 are associated with an increased sudden cardiac death risk in men (p=0.019, OR=1.7, 95% CI 1.1-2.8; p=0.011, OR=1.8, 95% CI 1.2-2.8, respectively). Genotype AG of rs499818 is associated with an increased sudden cardiac death risk in the women over 50 years old (p=0.009, OR=2.4, 95% CI 1.3-4.6). CONCLUSION Polymorphisms rs1333049 and rs10757278 are associated with SCD in men and rs499818 in the women aged over 50 years.

Abstract
Background and Objectives Genetic predisposition is an important risk factor for coronary artery disease (CAD). In this study, we aimed to evaluate the impact of rs10757274 and rs2383206 polymorphisms in chromosome 9p21 on presence and severity of CAD in a Turkish population. Subjects and Methods A total of 646 patients who underwent coronary angiography were included in this study. Coronary vessel score and Gensini score were calculated to assess the angiographic severity of CAD. Alleles of AA, AG, and GG were determined for rs10757274 (polymorphism-1) and rs2383206 (polymorphism-2) polymorphisms located in chromosome 9p21 from the blood samples. Results There was a significant difference between the alleles in polymorphism-1 in the presence of coronary artery disease (38.9% in AA, 48.0% in GG and 56.4% in AG, p=0.017). However, there was no difference between the alleles in polymorphism-2. According to vessel scores, there was a significant difference between the alleles in polymorphism-1 (AA 0.71±1.04, GG 0.88±1.07, AG 1.06±1.12, p=0.018). In polymorphism-2, vessel scores did not show a difference between the alleles. In polymorphism-1, there was a significant difference in Gensini score (p=0.041). Gensini scores did not differ between the alleles in polymorphism-2 (p>0.05 for all). In multivariate analyses, none of the alleles was an independent factor for presence of CAD. Conclusion The presence of rs10757274 polymorphism including AG allele in chromosome 9p21 was related to CAD. However, this relationship was not independent of other cardiovascular risk factors.

Abstract
Recent genome-wide association studies identified the common genetic variants in 9p21 were associated with the coronary artery disease (CAD). However, whether this locus could predict the severity of CAD in Chinese Han population is unclear. 499 CAD patients who underwent coronary angiography (CAG) have been enrolled for this study. The single-nucleotide polymorphisms rs2383207 and rs2383206 in 9p21 were genotyped in 499 CAG cases and 1519 controls in Chinese Han population. The gene dosage of 9p21 was stratified by the degree of vascular lesions and tested for association with the severity of CAD. Rs2383207 and rs2383206 demonstrated significant associations with 2-vessel and 3-vessel disease (P = 2.0×10(-3) and 1.9×10(-4) , respectively). GG genotypes of rs2383206 occurred higher proportion of left main trunk (LM) disease (P = 6.0×10(-3) ). GG genotypes of rs2383207 occurred higher proportion of left anterior descending artery disease (LAD) and right CAD (RCA) (P = 2.7×10(-6) and 1.6×10(-4) , respectively). The risk allele G of rs2383207 was associated with severity of CAD estimated by the Gensini score (P = 3.6×10(-5) ). Rs2383207 may strongly influence the development of CAD in Chinese Han population. The gene dosage in 9p21 could predict the severity of CAD.

Abstract
OBJECTIVES Hypertension (HT) is a complex disorder influenced by both genetic and environmental factors. Recent genome-wide association studies have identified a major risk locus for atherosclerosis on chromosome 9p21.3. SNPs within the coding sequences of CDKN2A/B and the long non-coding RNA CDKN2B-AS1 could potentially contribute to HT development. Thus, this study aimed to investigate whether the frequency of four SNPs on chromosome 9p21.3 affects blood pressure (BP) levels in Turkish HT patients, and to examine correlations between these SNPs, specific SNP haplotypes, and HT. DESIGN AND METHODS This is a case-control study comparing HT patients and healthy controls. Real-time polymerase chain reaction (RT-PCR) analysis was utilized to detect SNPs rs10757274, rs2383207, rs10757278, and rs1333049 in 170 HT patients and 180 healthy controls. RESULTS Each SNP was detected at significantly higher frequencies in HT patients than in controls (p values 0.001); however, there was no significant link between rs10757274, rs2383207, rs10757278, and rs1333049 SNPs and HT grades. Furthermore, there was a significant association between elevated systolic BP levels and rs1333049 GG genotype (p=0.047), while weight gain and increased fasting glucose levels were significantly associated with rs2383207 AA genotype (p=0.020 and p=0.009, respectively). Lastly, we detected a correlation between GG, GA, and AG haplotypes in block 1 (rs10757274, rs2383207) and GC and AG haplotypes in block 2 (rs10757278, rs1333049) and HT. CONCLUSIONS Our findings suggest that SNPs rs10757274, rs2383207, rs10757278, and rs1333049, particularly those within the CDKN2B-AS1 gene, and related haplotypes may confer increased susceptibility to HT development.
