Abstract
Diabetes mellitus is an increasingly prevalent metabolic disorder characterized by chronic hyperglycemia and impaired insulin action. Although the pathogenesis of diabetes is multifactorial, emerging evidence suggests that chronic low-grade inflammation plays a significant role in the development and progression of the disease. The cyclic GMP-AMP synthase (cGAS) and its downstream signaling pathway, the stimulator of interferon genes (STING), have recently gained attention in the field of diabetes research. This article aims to provide an overview of the role of cGAS-STING in diabetes, focusing on its involvement in the regulation of immune responses, inflammation, insulin resistance, and β-cell dysfunction. Understanding the contribution of cGAS-STING signaling in diabetes may lead to the development of targeted therapeutic strategies for this prevalent metabolic disorder. The results section presents key findings from multiple studies on the impact of STING in diabetes. It discusses the influence of STING on inflammation levels within a diabetic environment, its effect on insulin resistance, and its implications for the development and progression of diabetes. The cGAS-STING signaling pathway plays a crucial role in the development and progression of diabetes.

Abstract
INTRODUCTION Abnormalities in the maternal immune system and insufficient gestational immune tolerance may significantly contribute to the development of preeclampsia (PE). The NLR family pyrin domain containing 3 (NLRP3) functions as a pattern recognition receptor that identifies pathogen-associated molecular patterns. Interleukin-4 (IL-4) is a potent anti-inflammatory cytokine that modulates the immune response. Therefore, this study aims to elucidate the impact of NLRP3 and IL-4 variable number of tandem repeats (VNTR) polymorphisms on susceptibility to PE. MATERIALS AND METHODS A total of 1,018 patients with PE and 1,007 normal pregnant women were recruited as the case group and the control group, respectively. Peripheral blood DNA was extracted, and NLRP3 and IL-4 VNTR polymorphisms were genotyped using polymerase chain reaction and gel electrophoresis. Genotypes and allele frequencies of pregnant women were assessed in both cohorts. RESULTS The NLRP3 VNTR 9-7 genotype in the PE group was significantly lower than that in the control group, but 9 and 14 allele frequencies were significantly higher in patients with PE. Individuals with IL-4 VNTR genotypes 1-2 had a lower risk of PE than controls, and the IL-4 VNTR 2 allele frequency was significantly lower in patients with PE. CONCLUSIONS This study, the first of its kind in the literature, evaluates the impact of NLRP3 VNTR and IL-4 VNTR polymorphisms on PE, revealing a significant correlation with PE susceptibility. This investigation contributes to understanding the pathogenesis of PE and provides a reference point for developing strategies to prevent and treat the disease in the future.

Abstract
Interleukin-1β (IL-1β), vascular endothelial growth factor (VEGF), and IL-4 serum levels and new genetic mutations in breast cancer (BC) patients were assessed in the current study. The serum levels of the examined cytokines in 40 BC patients and 40 control subjects were assessed using the ELISA technique. In order to identify genotype variants of the IL-1β, IL-4, and VEGF genes in 40 Formalin Fixed Paraffin Embedded (FFPE) samples with BC and 10 FFPE samples from healthy women's breast tissue, Sanger sequencing was used. According to this study, BC patients had significantly lower serum concentrations of IL-4 and significantly higher quantities of the tumor markers, CA15-3, IL-1β, and VEGF. In terms of genotype alterations, a total of 21 mutations in three trialed genes (eight in IL-1β, 10 in IL-4, and three in VEGF) were found in BC patients. The results of the current investigation suggested that angiogenesis and the development of BC may be significantly influenced by the genetic differences and higher levels of the examined cytokines.

Abstract
BACKGROUND Preeclampsia (PE) is a syndromic disorder that affects 2% to 8% of pregnancies and is diagnosed principally when hypertension appears in the second-d half of pregnancy. WHO estimates the incidence of PE to be seven times higher in developing countries than in developed countries. Severe preeclampsia/eclampsia is one of the most important causes of maternal mortality, associated with 50,000 to 100,000 annual deaths globally as well as serious fetal and neonatal morbidity and mortality, especially in developing countries. Even though evidence from family-based studies suggest PE has a heritable component, its etiology, and specific genetic contributions remain unclear. Many studies examining the genetic factors contributing to PE have been conducted, most of them are focused on single nucleotide polymorphisms (SNPs). Given that PE has a very important inflammatory component, is mandatory to examine cytokine-SNPs for elucidating all mechanisms involved in this pathology. In this review, we describe the most important cytokine-polymorphisms associated with the onset and development of PE. We aim to provide current and relevant evidence in this regard. METHODS We searched English databases such as PubMed and the National Center for Biotechnology Information. The publication time of the papers was set from the establishment of the databases to February 2022. All studies about Th1/Th2/Th17 cytokines polymorphisms were included in our study. RESULTS SNPs in IFN-γ, TNF-α, IL-4, IL-6, IL-10, IL-17A, and IL-22 are associated with the development, early-onset and severity of PE, being the Th1/Th2/Th17 responses affected by the presence of these SNPs. CONCLUSIONS The changes in Th1/Th2/Th17 response modify processes such as placentation, control of inflammation, and vascular function. Nonetheless, association studies have shown different results depending on sample size, diagnostic, and population.

Abstract
Women live longer than men but experience greater disability and a longer period of illness as they age. Despite clear sex differences in aging, the impact of pregnancy and its complications, such as preeclampsia, on aging is an underexplored area of geroscience. This review summarizes our current knowledge about the complex links between pregnancy and age-related diseases, including evidence from epidemiology, clinical research, and genetics. We discuss the relationship between normal and pathological pregnancy and maternal aging, using preeclampsia as a primary example. We review the results of human genetics studies of preeclampsia, including genome wide association studies (GWAS), and attempted to catalog genes involved in preeclampsia as a gateway to mechanisms underlying an increased risk of later life cardio- and neuro- vascular events. Lastly, we discuss challenges in interpreting the GWAS of preeclampsia and provide a functional genomics framework for future research needed to fully realize the promise of GWAS in identifying targets for geroprotective prevention and therapeutics against preeclampsia.

Abstract
Although a number of theories have been suggested, including roles for oxidative stress, an abnormal maternal-fetal interface, and genetic and environmental factors, the etiopathology of pre-eclampsia (PE) remains unclear. Maternal immune tolerance is important for maintaining pregnancy, and researchers have increasingly focused on the critical roles of cytokines in the pathogenesis of PE in recent years. The assessment of candidate genetic polymorphisms in PE could partially elucidate the mechanisms of susceptibility to disease, and contribute to seeking for new diagnosis and treatment methods of PE. PE can lead to severe complications, and even the death of both mother and fetus. Although the complex pathology is not yet clear, some evidence suggested that the occurrence of PE is related to inflammatory factors. We reviewed the current understandings of roles of cytokines in PE, and provided an extensive overview of the role of single nucleotide chain polymorphisms (SNPs) in the genes potentially underlying the pathophysiology of PE.

Abstract
OBJECTIVE To determine association between IL-32 gene polymorphism, and serum levels of IL-32 and susceptibility to preeclampsia (PE). METHODS The frequency of IL-32 rs9927163 and rs4786370 polymorphisms was determined by PCR-RFLP. Also ELISA was used to determine the levels of serum IL-32. RESULTS Regarding rs4786370 C/T SNPs, the frequencies of CT, TT genotypes, and T allele were shown to be higher in the PE patients. IL-32 serum level significantly increased in the PE patients. CONCLUSION Variety of allele and genotype IL32 rs4786370 as well as a rise in serum level of IL-32 can be regarded as a risk factor for PE.

Abstract
BACKGROUND Interleukin 4 (IL4) is a key cytokine that regulates the inflammatory cascade in bronchial asthma. We investigated the association between the IL4 and IL4R polymorphisms and the susceptibility for bronchial asthma among Egyptian children. METHODS IL4 VNTR and IL4R c.1902 A>G p.(Q576R) polymorphisms were investigated among 100 children with bronchial asthma and 100 healthy controls using PCR method. Serum levels of IL4 and immunoglobulin E (IgE) were assessed by ELISA. RESULTS The frequencies of (A1A2 + A2A2) genotypes and A2-allele of the IL4 VNTR variant were significantly higher among asthmatic patients than controls (p = 0.01, OR = 2.34, 95% CI = 1.24-4.44; p = 0.01, OR = 2.27, 95% CI = 1.29-3.99, respectively). The frequencies of (AG + GG) genotypes and G-allele of the IL4R (A1902G) variant were significantly higher among asthmatic patients than controls (p = 0.003, OR = 2.52, 95% CI = 1.39-4.58; p = 0.002, OR = 2.25, 95% CI = 1.35-3.76, respectively). There was a significant association between (A1A2 + A2A2) genotypes of the IL4 VNTR variant and high serum IL4 level among asthmatic patients (p < 0.001). The (AG + GG) genotypes of the IL4R (A1902G) variant were significantly associated with exposure to triggers, atopic dermatitis and higher serum IgE level in asthmatic patients (p = 0.02, 0.04 and 0.01, respectively). CONCLUSION IL4 VNTR and IL4R (A1902G) polymorphisms could be associated with higher risks of bronchial asthma among Egyptian children.

Abstract
Simple Summary The IL-4 and IL-4R cytokine genes are responsible for immune response in the reproductive system and are related to embryonic implantation and fetal survival during pregnancy in females. However, to date, their effects on litter size traits in pigs have been not elucidated. Therefore, the present study was conducted to verify the porcine IL-4 and IL-4R polymorphisms and assess how they affect litter size traits in commercial pigs. The findings suggested that the porcine IL-4 g.134993898T > C and IL-4R c.1577A > T polymorphisms were associated with the litter size traits. Therefore, the porcine IL-4 and IL-4R genes may be potentially effective genetic markers to improve the litter size traits in pigs. Abstract The interleukin-4 (IL-4) and interleukin-4 receptor (IL-4R) are cytokines that are involved in the immune and reproductive systems. This study aimed to verify the polymorphisms in the porcine IL-4 and IL-4R genes and to assess their effects on litter size traits in commercial pigs. Single nucleotide polymorphisms (SNPs) in the porcine IL-4 and IL-4R genes were genotyped by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. A non-coding SNP of IL-4 g.134993898T > C and a non-synonymous SNP of IL-4R c.1577A > T (amino acid change at position 526, Q526L) were found to be segregating in Landrace sows. The IL-4 g.134993898T > C polymorphism was significantly associated with the number of piglets weaned alive (NWA) trait. The IL-4R c.1577A > T polymorphism was significantly associated with the number born alive (NBA) and NWA traits. Moreover, the accumulation of favorable alleles of these two SNP markers revealed significant associations with the NBA, NWA, and mean weight of piglets at weaning (MWW) traits. These findings indicate that the porcine IL-4 and IL-4R genes may contribute to the reproductive traits of pigs and could be used as candidate genes to improve litter size traits in the pig breeding industry.

Abstract
Colorectal cancer (CRC) is one of the most common malignancies worldwide. Genetic variations in cytokine genes and their receptors lead to the severity of the disease. The interleukin-1 receptor antagonist (IL1RN) is a cytokine that inhibits interleukin-1 (IL-1) activity by binding to IL-1 receptors. Also, interleukin-4 (IL-4) is an anti-inflammatory cytokine that can play an important role in several cancers. The present case-control study was aimed to evaluate the association of IL-4 and IL1RN VNTR polymorphisms with the susceptibility to CRC in a sample of Iranian population provided by the Research Center for Gastroenterology and Liver Disease at Taleghani Hospital, Tehran. A total of 123 patients diagnosed with CRC and 152 healthy controls were recruited in the present study. Genomic DNA was extracted by salting out method from whole blood and genotyping of IL1RN and IL-4 VNTR polymorphisms were determined by PCR-based technology. Our study manifested the frequency of 1/2 and 2/4 genotypes of IL1RN 68bp VNTR polymorphism are significantly different between both groups (p = 0.0001 and p = 0.01 respectively). However, we could not find any correlation between IL-4 VNTR polymorphism and CRC cancer. It seems that 1/2 and 2/4 genotypes of IL1RN are correlated with CRC susceptibility in our population, although, more studies are needed to confirm our results.

Abstract
Backgrounds Breast cancer (BC) is one of the most widespread cancers globally. Understanding the etiology of BC may help in determining the various risk factors involved in its malignancy. Certain genetic mutations are considered to play a key role in increasing the risk of BC. Objectives In this study, we explored the correlation between a variable number tandem repeat (VNTR) polymorphism in the IL-4 gene and BC. Methods PCR and subsequent gel electrophoresis were used to genotype this variant in 360 Jordanian women (180 BC patients and 180 controls). In addition, phenotype–genotype analysis was carried out. Results Our findings illustrate that there is no significant relationship between the variant genotypes in the IL-4 gene and BC among Jordanian females. Other than body mass index and tumor differentiation (p< 0.05), none of the clinical and pathological parameters of BC patients exhibited any association with the variant genotypes. Conclusions From this study, we propose that the IL-4 genetic variant does not impact BC development and progression but that it could influence the disease prognosis.

Abstract
Type 2 diabetes mellitus (T2DM) has multigenetic and environmental interactive factors. Although diabetic neuropathies (DPN) are the most common, but at the same time, the least recognized and understood long-term complication of diabetes. This study aimed to investigate the association of IL-4 VNTR gene polymorphism with T2DM complicated with neuropathy in Egyptian subjects. This is a case control study including 102 T2DM Egyptian patients, plus 188 unrelated healthy individuals as controls. They were evaluated for variable number tandem repeat (VNTR); 70 base pair repeats located in the intron 3; of IL-4 gene using the PCR technique. Homozygote frequency of the three-repeat allele (A1/A1) genotype of IL-4 VNTR was nearly equal among diabetic cases and controls (60.8% vs. 62.2%, respectively). Heterozygous frequency of (A1/A2) genotype was higher among controls compared to cases (33.5% vs. 19.6%, respectively) but not statistically significant. The (A2) allele had a significantly higher frequency in diabetic cases compared to controls (29.3% vs. 21.0%, respectively) while the (A1) allele had lower frequency but not significant one (70.7% vs. 79.0%, respectively). Comparing cases complicated with diabetic neuropathy vs. noncomplicated cases regarding their polymorphic IL-4 (VNTR) genotypes revealed a nonsignificant lower frequency of (A1A1) genotype (57.1% vs. 65.1%, respectively, p = .57) with a higher combined (A2A2 + A1/A2) genotype frequency (42.9% vs. 34.9%, respectively). Only two haplotypes (A1) & (A2) of IL-4 (VNTR) gene were recognized among Egyptian population; (A2) allele may influence in diabetes but not its complication (neuropathy) among Egyptian diabetic patients.

Abstract
Preeclampsia is a multi-system hypertensive disorder of pregnancy, with significant rates of maternal and neonatal morbidity. It represents a major cause of preterm birth, as definitive treatment demands fetal delivery. Although its pathophysiology is complicated, placental hypoxia and endothelial dysfunction constitute established pathogenetic steps of the disease. Inflammation is considered to be a crucial mediator of preeclampsia process, as an imbalance between TH 1, TH 2, and TH 17 immune responses is observed. The present review accumulates current knowledge about the contribution of interleukins in preeclampsia, summarizing the pathways through which each interleukin exerts its function in the disease. Also, the role of genetic polymorphisms is explored and the predictive efficacy of maternal serum interleukin levels is evaluated. Finally, recommendations about the safe interpretation of the outcomes, as well as guidance for future research, are provided.

Abstract
Clinical outcome of T2DM can be influenced by a polymorphism of different cytokines. The aim of this study was to evaluate the effect of genetic variation and gene expression of IL-4 in T2DM patients. This study was carried out on type II diabetic patients and healthy people served as controls. All subjects were submitted to estimation of IL-4 gene polymorphism using VNTR PCR method and gene expression by real-time PCR. There was a significant decrease of IL-4 gene expression and serum IL4 levels in subjects with B2B2 genotypes. A significant positive correlation was found between IL-4 gene expression and the HDL-c levels and negative correlation between serum IL4 levels and LDLc. Also, a negative correlation was found between serum IL4 and gene expression with both systolic and diastolic blood pressure levels in patients group. It can be concluded that IL-4 gene expression and serum IL4 reduction in patients with B2B2 genotypes has a relation to dyslipidemia and hypertension in the patient with type 2 diabetes mellitus.

Abstract
PURPOSE OF REVIEW Regardless of the familial linkage reported in pre-eclampsia development, understanding the polymorphic genes associated with pre-eclampsia remains limited. Hence, this review aims to outline the main genetic factors that have been investigated in respect to pre-eclampsia development. RECENT FINDINGS It is apparent that different genes show significance in varying populations. Notably, it is reported that apolipoprotein-1 gene polymorphisms are associated with pre-eclampsia development in an African-American population, which may be worthwhile to investigate in a Black South African cohort. Despite the research attention that is focused on this surreptitious syndrome, a definitive cause eludes scientists and physicians, alike. Genetic studies can fulfil a dual purpose of suggesting novel hypotheses through genome-wide screening and testing these hypotheses via candidate gene studies. However, publications to date have only presented inconsistent and conflicting results regarding candidate gene analysis.

Abstract
Familial Mediterranean fever (FMF) is an autoinflammatory disorder. It is caused by mutations in the MEFV gene encoding the pyrin protein, which regulates the innate inflammatory response. The aim of the current study was to investigate the relationship between serum Interleukin-4 (IL-4) and its gene polymorphism, namely rs79071878, and FMF occurrence, severity, and response to treatment in Egyptian children harboring the disease. Fifty Egyptian children diagnosed as having FMF were included in this study. They were divided equally into two groups according to disease activity. Forty controls, age- and gender-matched, were also included. Serum IL-4 levels were measured by enzyme-linked immunosorbent assay (ELISA). The IL-4 rs79071878 polymorphism was determined by polymerase chain reaction (PCR) analysis. There was no significant difference in genotype distribution of IL-4 gene rs79071878 between patients and controls (p = 0.286) and had no correlation with FMF severity or response to colchicine therapy. Serum IL-4 level had no significant difference between children with FMF attack and those in attack-free period compared to controls (p = 0. 794) and had no correlation with any of demographic, or clinical characteristics, disease severity, or response to colchicine therapy. Serum IL-4 level and its gene polymorphism were not found to have any increase risk of FMF occurrence, disease severity, or response to treatment in the Egyptian children. Further studies are needed to verify these results.

Abstract
MicroRNAs (miRNAs) are a class of noncoding small RNAs which regulate gene expression through post-transcriptional repression or degradation of messenger RNA. They play very important roles in various biological processes including growth, differentiation, and proliferation, as well as apoptosis, angiogenesis, and metabolism. Therefore, in the present study, we evaluated the possible effect of functional rs7372209C/T polymorphism in the 5'- region of pri-miRNA- 26a1gene on preeclampsia(PE) susceptibility. This case-control study was conducted on 219 PE women and 204 unrelated healthy controls. The amplification refractory mutation system-polymerase chain reaction method was used for rs7372209C/T genotyping. The pri-miRNA- 26a1 rs7372209CT genotype was associated with decreased PE risk (OR, 0.5 [95% CI, 0.3-0.8], P = 0.001). The frequency of rs7372209TT genotype did not differ between two groups. In addition, the pri-miRNA- 26a1 rs7372209 polymorphism was associated with lower risk of PE in dominant model (CT+TT vs CC) (OR, 0.5 [95% CI, 0.4-0.8], P = 0.002). Although there was no significant difference between mild and severe PE women according to rs7372209CT genotype, the differences between mild and severe PE groups with controls remained significant. The frequency of pri-miRNA-26a1 rs7372209CT genotype was not different between late-onset PE and early onset PE groups. The present study showed for the first time that the pri-miRNA- 26a1 rs7372209 polymorphism was associated with lower risk of mild and severe PE in the dominant model and this polymorphism could be a protective factor for PE susceptibility.

Abstract
Cancer incidence is dramatically increasing worldwide, therefore improved prediction and therapeutic methods are needed. Single nucleotide polymorphisms in cytokine genes may contribute to carcinogenesis. Interleukin (IL)-4 gene polymorphisms have been intensively studied with regard to their associations with cancer. However, the results of these previous studies remain inconclusive. The present study, therefore, aimed to conduct a meta-analysis of previously published studies in order to clarify the association of IL-4 with cancer risk. Eligible published articles were searched in Medline, PubMed, Embase and China National Knowledge Infrastructure databases up to March 2016. Odds ratios and 95% confidence intervals were used to identify potential associations between IL-4 genetic polymorphisms and the risk of cancer. A meta-analysis was then performed on 10,873 patients and 14,328 controls for IL-4 rs2243250 polymorphism, 3,970 patients and 5,686 controls for IL-4 rs2070874 polymorphism, and 1,896 patients and 2,526 controls for IL-4 rs79071878 polymorphism. A significant association with cancer risk was observed for rs2243250 and rs79071878 polymorphisms. In the subgroup analysis by cancer type, rs2243250 polymorphism was demonstrated to be associated with an increased risk of gastric cancer and breast cancer, rs2070874 polymorphism was correlated with leukemia and oral carcinoma, and rs79071878 polymorphism was relevant to bladder carcinoma risk. In the subgroup analysis by ethnicity, IL-4 rs2243250 polymorphism was demonstrated to be associated with cancer risk in both Caucasian and Asian populations, rs2070874 was associated with cancer risk in Asian populations, while rs79071878 polymorphism was associated with cancer risk in Caucasian populations. In conclusion, the present results suggested that the IL-4 rs2243250 and rs79071878 polymorphisms were associated with cancer susceptibility. Further subgroup analyses revealed that the effects of IL-4 gene polymorphisms on cancer risk may vary by cancer type and by ethnicity.

Abstract
Background & objectives: Interleukin-1 (IL-1) is one of the pro-inflammatory cytokines that plays a main role in the regulation of immune and inflammatory responses. Interleukin 4 (IL-4) as an anti-inflammatory cytokine regulates balance between Th1 and Th2 immune responses. This study was undertaken to investigate the IL-1β and IL-4 genes polymorphisms in patients with systemic lupus erythematosus (SLE) and also association between the polymorphisms and susceptibility to SLE. Methods: One hundred and sixty three SLE patients and 180 healthy controls were genotyped for the IL-4 VNTR (variable number tandem repeat), IL-1β C-511T and IL-1β T-31C polymorphisms by polymerase chain reaction (PCR) or PCR-RFLP (restriction fragment length polymorphism) method. Results: The frequencies of CC genotype and C allele of the IL-1β T-31C polymorphism were significantly (P<0.01) lower in SLE patients than controls. Moreover, the frequencies of RP1/RP2 genotype and RP2 allele of IL-4 VNTR polymorphism were significantly (P<0.05) higher in the SLE patients. No association was observed between IL-1β C-511T polymorphism and increased risk of SLE. We observed increased frequency of CT and TT genotypes of IL-1β C-511T polymorphism in SLE patients with malar rash compared to SLE patients without this manifestation. Interpretation & conclusions: The present findings suggest that IL-1β T-31C and IL-4 VNTR polymorphisms but not IL-1β C-511T polymorphism may contribute in SLE pathogenesis. In addition, CT and TT genotypes of IL-1β C-511T polymorphism were associated with SLE.

Abstract
Cytokines expression can be influenced by polymorphisms in their respective coding genes. We associated the CTI/TTD haplotype (Hap-1) and TCI/CCI haplotype (Hap-2) in the IL4 gene formed by the -590, +33 and variable number of tandem repeat polymorphisms with the severity of chronic periodontitis in humans. The functionality of these IL4 haplotypes in the response of immune cells to phorbol 12-myristate 13-acetate (PMA) with Ionomycin and IL-1β (as inflammatory stimuli) was evaluated. Gene expression (quantitative real-time PCR), profile of secreted cytokines (multiplex) and phenotypic polarization of T cells (flow cytometry) were the outcomes assessed. Green fluorescent protein reporter plasmid constructs containing specific IL4 haplotype were transiently transfected into JM cells to assess the influence of the individual haplotypes on promoter activity. In response to inflammatory stimuli the immune cells from Hap-1 haplotype had increased expression of anti-inflammatory IL4; conversely, the Hap-2 haplotype showed higher levels of pro-inflammatory cytokines. The haplotype CTI proved to be the most important for the regulation of IL4 promoter, regardless of the nature of the inflammatory stimulation; whereas the polymorphism in the promoter region had the least functional effect. In conclusion, IL4 haplotypes studied are functional and trigger opposite immune responses: anti-inflammatory (Hap-1) and pro-inflammatory (Hap-2). In addition, we identified the CTI haplotype as the main responsible for the regulation of IL4 transcriptional activity.

Abstract
Interleukin-1 receptor antagonist (IL1RA) intron 2 86 bp repeat and interleukin-4 (IL4) intron 3 70 bp repeat are variable number tandem repeats (VNTRs) that have been associated with various diseases, but their role in obesity is elusive. The objective of this study was to investigate the association of IL1RA and IL4 VNTRs with obesity and adiposity in 315 Malaysian subjects (128 M/187 F; 23 Malays/251 ethnic Chinese/41 ethnic Indians). The allelic distributions of IL1RA and IL4 were significantly different among ethnicities, and the alleles were associated with total body fat (TBF) classes. Individuals with IL1RA I/II genotype or allele II had greater risk of having higher overall adiposity, relative to those having the I/I genotype or I allele, respectively, even after controlling for ethnicity [Odds Ratio (OR) of I/II genotype = 12.21 (CI = 2.54, 58.79; p = 0.002); II allele = 5.78 (CI = 1.73, 19.29; p = 0.004)]. However, IL4 VNTR B2 allele was only significantly associated with overall adiposity status before adjusting for ethnicity [OR = 1.53 (CI = 1.04, 2.23; p = 0.03)]. Individuals with IL1RA II allele had significantly higher TBF than those with I allele (31.79 ± 2.52 versus 23.51 ± 0.40; p = 0.005). Taken together, IL1RA intron 2 VNTR seems to be a genetic marker for overall adiposity status in Malaysian subjects.
