Abstract
Background Polymorphisms in the lipoprotein lipase (LPL) and apolipoprotein CII (APO CII) genes have been linked to severe hypertriglyceridemia in several populations. This study investigated the frequency of LPL-Hind lll and APO Cll-Ava ll polymorphism among Kurdish patients with severe hypertriglyceridemia. Methodology We investigated LPL-Hind llland APO Cll-Ava ll gene polymorphism in a sample of Kurdish patients receiving treatment at Azadi Teaching Hospital in Duhok, Kurdistan Region, Iraq. We included a total of 100 subjects in this study, of which 64 had severe hypertriglyceridemia, and 36 had normotriglyceridemia. There were 56 males and 44 females. We used the polymerase chain reaction-restriction fragment length polymorphism technique to determine the polymorphism of the LPL-Hind lll and APO Cll-Ava ll genes. Results In those with severe hypertriglyceridemia, the most frequent alleles were H+H+ LPL-Hind lll polymorphism (42, 65.6%) followed by A1A1 APO Cll-Ava ll polymorphism (30, 46.9%), whereas these frequencies were 16 (44.4%) and 6 (16.7%) in those with normotriglyceridemia, respectively. The H+H+ genotype group had considerably higher triglyceride levels and lower high-density lipoprotein cholesterol levels compared with the H-H- genotype group. A similar pattern was observed when comparing the A1A1 and A2A2 genotype groups, with both patterns being statistically significant. Conclusions Our results showed a high frequency of H+H+ LPL-Hind III polymorphism in those with hypertriglyceridemia, which may be a hereditary indicator of vulnerability to this condition in the Kurdish population.

Genetic determinants of intracranial large artery stenosis in the northern Manhattan study. J Neurol Sci 2022; 436:120218. [PMID: 35259553 PMCID: PMC9018518 DOI: 10.1016/j.jns.2022.120218] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2021] [Accepted: 03/01/2022] [Indexed: 12/31/2022]
Abstract
BACKGROUND Intracranial stenosis is one of the most common causes of stroke worldwide. Several single nucleotide polymorphisms have been associated with intracranial atherosclerosis, which is inferred to be the most common underlying cause of intracranial large artery stenosis (ILAS). We previously reviewed known genetic variants related to ILAS in predominantly Asian cohorts, but their prevalence and role in ILAS among western multiethnic populations are uncertain. METHODS We leveraged existing imaging and genetic data from the Northern Manhattan Study, a multiethnic prospective cohort study. Based on literature review, we selected adiponectin Q (ADIPOQ) rs2241767 and rs182052, ring finger protein 213 (RNF213) rs112735431, apolipoprotein E (APOE) rs429358, phosphodiesterase 4D (PDE4D) rs2910829, lipoprotein lipase (LPL) rs320, and aldosterone synthase (CYP11B2) rs1799998 variants as candidates to explore. We defined ILAS as luminal stenosis >50% in any intracranial large artery using time-of-flight magnetic resonance angiography (MRA). RESULTS We included 1109 participants (mean age 70 ± 9 years, 70% Hispanic, 60% women) in this study. ILAS was identified in 81 (7%) NOMAS participants. Logistic regression analyses adjusted for age, sex, principal components, and vascular risk factors showed ILAS prevalence associated with CYP11B2 rs1799998 under the dominant model (OR = 0.56, 95%CI: 0.35-0.89) and LPL rs320 heterozygote genotype (OR = 1.68, 95%CI: 1.05-2.71). The genotype distributions of ADIPOQ rs2241767 and rs182052, APOE rs429358 and CYP11B2 rs1799998 variants were significantly different among non-Hispanic white and Black, and Hispanic groups. When participants were further stratified by race/ethnicity, the estimates were consistent for CYP11B2 rs1799998 across race/ethnic groups but not for LPL rs320. CONCLUSION The CYP11B2 rs1799998 variant may be a protective genetic factor for ILAS across race/ethnic groups, but the risk of ILAS associated with LPL rs320 varies by race/ethnic group. Further functional studies may help elucidate the role that these variants play in the pathophysiology of ILAS.

Genes (Basel) 2022; 13:genes13040664. [PMID: 35456470 PMCID: PMC9024856 DOI: 10.3390/genes13040664] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Revised: 04/06/2022] [Accepted: 04/07/2022] [Indexed: 11/22/2022] Open
Abstract
Lipoprotein lipase (LPL) is responsible for the hydrolysis of lipoproteins; hence defective LPL is associated with metabolic disorders. Here, we identify certain intronic insertions and deletions (InDels) and single nucleotide polymorphisms (SNPs) in intron 6 of the LPL gene and investigate their associations with different phenotypic characteristics in a cohort of the general Kuwaiti population. Two specific regions of intron 6 of the LPL gene, which contain InDels, were amplified via Sanger sequencing in 729 subjects. Genotypic and allelic frequencies were estimated, and genetic modeling was used to investigate genetic associations of the identified variants with lipid profile, body mass index (BMI), and risk of coronary heart disease (CHD). A total of 16 variants were identified, including 2 InDels, 2 novel SNPs, and 12 known SNPs. The most common variants observed among the population were rs293, rs274, rs295, and rs294. The rs293 “A” insertion showed a significant positive correlation with elevated LDL levels, while rs295 was significantly associated with increased BMI. The rs274 and rs294 variants showed a protective effect of the minor allele with decreased CHD prevalence. These findings shed light on the possible role of LPL intronic variants on metabolic disorders.

Assessment of genetic polymorphism associated with ATP-binding cassette transporter A1 (ABCA1) gene and fluctuations in serum lipid profile levels in patients with coronary artery disease. Saudi Pharm J 2022; 29:1458-1465. [PMID: 35002384 PMCID: PMC8720826 DOI: 10.1016/j.jsps.2021.11.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2021] [Accepted: 11/10/2021] [Indexed: 01/12/2023] Open
Abstract
Background Coronary artery disease (CAD) is one of the common genetic and clinical risk factors associated with cardiovascular and multifactorial disorder. ATP-binding cassette transporter A1 (ABCA1) gene plays an important role in lipid metabolism and in multiple studies associated with CAD. However, more studies are needed to identify the exact role of single nucleotide polymorphisms which may cause CAD. Objectives The aim of this study is to investigate the genetic association of polymorphism g.1051G > A in the ABCA1 gene with CAD patients in the Saudi population. Methods We included 315 confirmed CAD cases, and 205 non-CAD or control subjects in this case-control study. DNA isolation was carried out for all registered participants and the polymorphism g.1051G > A was genotyped with Polymerase Chain Reaction followed by Restriction Fragment Length Polymorphism analysis with EcoNI restriction enzyme. Results Modifiable risk factors such as Body Mass Index, smoking and diabetes were strongly associated and non-modifiable risk factors such as hypertension (Systolic Blood Pressure and Diastolic Blood Pressure) and serum analysis such as Fasting Blood Glucose, Total cholesterol (TC), Triglyceride (TG) and LDL-c were significantly associated in CAD cases (p < 0.05). Allele (OR-1.73;95% CI:1.33–2.26; p = 0.0004), GA vs GG (OR-2.26; 95% CI: 1.53–3.35; p = 0.0003 and dominant inheritance pattern (OR-2.23; 95% CI:1.56–3.20; p = 0.00009 was strongly associated with CAD cases and control subjects. The frequency level of use of atorvastatin was significantly different among GG, GA and AA subjects. Additionally, TC and TG levels were influenced by the presence of g.1051G > A polymorphism. Conclusion The polymorphism g.1051G > A in the gene ABCA1 is closely associated with the existence of the CAD subjects. This polymorphism could also affect the serum levels of the lipid profile, suggesting a possible occurrence of CAD in the Saudi population.

Coronary Artery Disease: Association Study of 5 Loci with Angiographic Indices of Disease Severity. DISEASE MARKERS 2021; 2021:5522539. [PMID: 34336004 PMCID: PMC8292076 DOI: 10.1155/2021/5522539] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/04/2021] [Revised: 05/22/2021] [Accepted: 07/01/2021] [Indexed: 01/11/2023]
Abstract
Background Different common gene variants were related to coronary artery disease (CAD) in many studies. Yet, the relation of these loci to the severity of CAD is not completely elucidated. Methods We enrolled 520 subjects (315 CAD cases and 205 controls). CAD presence and extension were assessed by coronary angiography (CAG). Genotyping of five SNPs (namely, rs2230806 (1051G > A) in ABCA1 on chromosome 9, rs2075291 (553G > T) in ApoA5 on chromosome 11, rs320 in LPL on chromosome 8 intron (T → G at position 481), rs10757278 (c.22114477A > G), and rs2383206 (c.22115026 A > G) on chromosome 9p21 locus) was performed by allele-specific PCR. The degree and site of arterial lesions were used to classify patients, tested for association with CAD severity, and related to allele dosage. Results The polymorphisms rs2383206 and rs10757278 showed significant associations with 2- and 3-vessel coronary disease (p =0.003 and 0.006, respectively). The homozygous GG genotypes of rs10757278 was associated with higher frequency of left anterior descending (LAD), right coronary artery (RCA) and left circumflex (LCX) diseases (p =0.002, 0.016 and 0.002, respectively). The GG genotypes of rs2383206 were found in higher percentage in patients with left main (LM) trunk and left circumflex (LCX) diseases (p = 0.013 and 0.002, respectively). Conclusion SNPs rs10757278 and rs2383206 allele dosage could predict CAD severity in the Saudi Arab population.

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.

Association between the lipoprotein lipase rs1534649 gene polymorphism in intron one with Body Mass Index and High Density Lipoprotein-Cholesterol. Saudi J Biol Sci 2021; 28:4717-4722. [PMID: 34354459 PMCID: PMC8324958 DOI: 10.1016/j.sjbs.2021.04.085] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Revised: 04/24/2021] [Accepted: 04/26/2021] [Indexed: 11/20/2022] Open
Abstract
Lipoprotein lipase (LPL) is an enzyme involved in lipid metabolism and distribution of fatty acids hence its role in the initiation and development of dyslipidemia and adiposity. Single nucleotide polymorphisms (SNPs) across the LPL gene have been associated with dyslipidemia, however, the association with obesity has been limited towards specific populations. This study examined the association between LPL gene polymorphisms with plasma lipid levels and body mass index (BMI) in the Kuwaiti population. We examined a total of 486 adults (303 and 183 females and males respectively) with plasma lipid levels and BMI. DNA samples were genotyped for two LPL gene polymorphisms (rs1534649 and rs28645722) using TaqMan allelic discrimination. The relationship between the genotypes with both plasma lipid levels and BMI were assessed using linear regression using “SNPassoc” package from R statistical software. Using an additive genetic model, linear regression analysis showed the T-allele of rs1534649 to be associated with increased BMI in a dose-dependent trend β = 2.13 (95% CI 1.33–2.94); p = 1.7 × 10−7. In addition, a borderline significance was observed between the T-allele and low levels of high density lipoprotein-cholesterol β = −0.04 (95% CI −0.08, −0.006); p = 0.02. There were no associations between rs28645722 and plasma lipid levels (p > 0.05). However, a trend was observed between the A-allele and increased BMI β = 1.75 (95% CI 0.14–3.35); p = 0.03. Our study shows intron one polymorphism rs1534649 to increase the risk of obesity and dyslipidemia. Our findings warrant further investigation of the mechanism of LPL on the development of obesity along with the role of intron one and its impact on LPL gene activity.
