The −1131C is a naturally occurring variant of the apolipoprotein A5 (ApoA5) gene, which has been shown to associate with increased triglyceride levels. This variant has also been shown to confer risk for development of ischemic heart disease and stroke. The gene is in linkage disequilibrium with factors known to correlate with impaired glucose homeostasis.(More)
BACKGROUND AND AIMS In recent studies, the T-1131C variant of apolipoprotein A5 (APOA5) gene was found to confer a risk for metabolic syndrome (MS). Here we determined four haplotype-tagging polymorphisms (T-1131C, IVS3+G476A, T1259C, and C56G), and studied the distribution of the naturally occurring major haplotype profiles in MS. METHODS AND RESULTS A(More)
OBJECTIVES Recently, an association was found between Crohn's disease and the interleukin-23 receptor (IL-23R) gene. Since the IL-23/IL-17 pathway is known to associate with other autoimmune diseases, including rheumatoid arthritis (RA) and systemic sclerosis (SSc), we hypothesised that IL-23R could be a shared susceptibility gene. METHODS Groups of(More)
OBJECTIVE Apolipoprotein A5 (APOA5) gene variants have been shown to be associated with elevated TG levels; the T-1131C (rs662799) variant has been reported to confer risk for the metabolic syndrome in adult populations. Little is known about the APOA5 variants in pediatric population, no such information is available for pediatric obesity at all. Here we(More)
Both the natural variants of the apolipoprotein A5 (APOA5) and the glucokinase regulatory protein gene (GCKR) have been shown to associate with increased fasting triglyceride levels. Here, we investigated the possible association of the functional variants of these two genes with non-fasting triglyceride levels and their susceptibility nature in ischemic(More)
OBJECTIVE Recently, the association of the natural variants rs1260326 and rs780094 of the glucokinase regulatory protein (GCKR) gene with increased fasting triglycerides and decreased fasting plasma glucose in diabetic adults was reported; the minor alleles were also found to reduce the risk of type 2 diabetes. The present study examined the possible(More)
AIM The goal of the current work was to analyse the prevalence of the +49A/G variant of the cytotoxic T-lymphocyte antigen 4 gene (CTLA4) in Hungarian patients with Crohnos disease (CD) and ulcerative colitis (UC). METHODS A total of 130 unrelated subjects with CD and 150 with UC, and 170 matched controls were genotyped for the single nucleotide(More)
BACKGROUND T-1131C, T1259C and IVS3+G476A are naturally occurring variants of the apolipoprotein A5 (APOA5) gene and their possible impact on the development of ischemic stroke was investigated in the present study. METHODS AND RESULTS PCR-RFLP assays were used to determine the distributions of the APOA5 alleles in small-vessel, large-vessel and mixed(More)
OBJECTIVE The galectin-2 protein is presumed to play a regulatory role in the intracellular trafficking of the lymphotoxin-alpha (LTA) cytokine. LTA is a pro-inflammatory factor, its 252GG homozygote variant is considered as a susceptibility factor for arteriosclerosis and cardiovascular diseases. By contrast, the galectin-2-encoding gene LGALS2 3279TT(More)
BACKGROUND Metabolic syndrome consists of multiple risk factors that are increasing the cardiovascular mortality. The T-1131C variant of the apolipoprotein A5 gene, associated with increased triglycerides, has been found to confer risk for cardiovascular diseases and metabolic syndrome. Because other naturally occurring variants of the gene also correlate(More)
