The human PCK1 gene encoding phosphoenolpyruvate carboxykinase (GTP) (PEPCK) was isolated and sequenced. There is 91% amino acid sequence identity (567/622 residues) between the human and the rat proteins, with conservation of intron/exon borders. A polymorphic dinucleotide microsatellite with the structure (CA)16(TA)5(CA) was identified in the 3' untranslated region of the cloned human PCK1 gene. This highly informative genetic marker has an estimated PIC value of 0.79 and heterozygosity of 0.81. Analysis of the RW pedigree demonstrated recombination between PCK1 and the MODY gene on chromosome 20. Multipoint linkage analysis of the reference pedigrees of the Centre d'Etude du Polymorphisme Humain localized PCK1 on the genetic map of chromosome 20 at a position distal to markers that are closely linked to MODY. PCK1 is part of a conserved linkage group on mouse Chromosome 2 with identical gene order but expanded length in the human genome.

PCR primers specific to the human liver fructose-1,6-bisphosphatase (FBP) gene were designed and used to isolate a cosmid clone. Physical mapping of the FBP cosmid by FISH, and genetic mapping of an associated GA repeat polymorphism (PIC = 0.35), located the liver FBP gene to chromosome 9q22.3 with no recombination between FBP and the index markers D9S196 (Zmax = 13.2), D9S280 (Zmax = 11.7), D9S287 (Zmax = 15.6), and D9S176 (Zmax = 14.4). Amplification using FBP exon-specific primers with a YAC contig from this region of chromosome 9 further refined the placement of FBP genomic sequences to an approximately 1.7-cM region flanked by D9S280 and D9S287, near the gene for Fanconi anemia group C. Precise localization of the FBP gene enabled evaluation of FBP as a candidate gene for maturity-onset diabetes of the young (MODY) and non-insulin-dependent diabetes (NIDDM) in both Caucasian and African-American families, using the highly informative markers D9S287 and D9S176. Although FBP is a rate-limiting enzyme in gluconeogenesis, using both parametric and nonparametric analysis there was no evidence for linkage of FBP to diabetes in these families.

Background and Objectives: Metabolic syndrome (MetS) is a multiple risk factor for atherosclerosis, cardiovascular disease, type 2 diabetes and strokes. One-third of middle-age women are at risk of MetS, which predisposes them to type 2 diabetes and cardiovascular disease. Changes in the regulation of anti-inflammatory cytokines-which play an important role in pathologic processes-may contribute to inflammatory disorders. Cytokine polymorphisms are known to have an impact on gene expression. The purpose of this study was to search for the relationship between the IFNG polymorphisms and the levels of proinflammatory cytokines. Materials and Methods: This study, conducted in West Pomeranian Voivodeship, Poland, involved 416 women. Of these women, 33.6% of them had primary education, 44.8% lived in cities with a population of over 100,000, and 82.7% were married. Of the participants, 28.4% met the criteria for MetS. The study involved: interview performed to collect sociodemographic and medical data, anthropometric measurements, as well as venous blood collection for biochemical analysis, genetic testing and the measurement of inflammatory markers. Results: The link between the IFNG (rs2430561) polymorphism and serum PIC (proinflammatory cytokines) levels was tested with regard to MetS. In the MetS+ subgroup, the T/T and A/T genotypes of the IFNG gene were accompanied by higher IL-6 levels than in the MetS- subgroup. Conclusion: Our study has not confirmed a direct link between the IFNG polymorphisms and the levels of inflammatory biomarkers. Nevertheless, the T/T and A/T genotypes of the IFNG gene may predispose to elevated IL-6 levels.
