The polymorphism at position 25 of the gene encoding transforming growth factor-beta1 (TGF-beta1), which changes the amino acid sequence of the signal peptide sequence (arginine to proline), is causing a variation in TGF-beta1 production. The homozygous genotype (Arg25Arg) is associated with higher TGF-beta1 production than the heterozygous (Arg25Pro)(More)
AIM Considerable attention is focused on polymorphisms in the gene encoding transforming growth factor-beta1 (TGF-beta1), a multifunctional cytokine that is in turn a potent growth inhibitor involved in wound healing and differentiation. In humans, it promotes the pathogenesis of organ fibrosis, atherosclerosis, cancer, autoimmune and inflammatory diseases,(More)
Clefts of the lip, alveolus, and palate (CLPs) rank among the most frequent and significant congenital malformations. Leu10Pro and Arg25Pro polymorphisms in the precursor region and Thr263Ile polymorphism in the prodomain of the transforming growth factor β1 (TGF-β1) gene have proved to be crucial to predisposition of several disorders. In this study,(More)
BACKGROUND Patients presenting with symptoms of lactose intolerance are in some centres routinely tested for a single-nucleotide polymorphism C-13910T, which is located upstream of the lactase gene (LCT) and is tightly associated with genetically determined lactase persistence/non-persistence. Typing of this polymorphism enables differential diagnosis for(More)
STUDY OBJECTIVES Pulmonary fibrosis develops in approximately 25% of patients with chronic sarcoidosis. Transforming growth factor (TGF)-beta1 plays a central role in fibrosis, and accruing reports address the implication of TGF-beta2 and TGF-beta3 in this process. We determined whether single-nucleotide polymorphisms (SNPs) in the TGF-beta1, TGF-beta2, and(More)
