Receptor for advanced glycation end products (RAGE) and glyoxalase I gene polymorphisms in pathological pregnancy

Abstract Objectives The aim of the study was to analyze polymorphisms of receptor for advanced glycation end products (RAGE) gene, and glyoxalase I gene and soluble RAGE, sRAGE, in physiological and pathological pregnancy. Design and methods Polymorphisms of RAGE gene (− 429 T/C, − 374 T/A, 557 G/A, 2184 A/G) and glyoxalase I gene (A419C) and sRAGE serum levels were determined in 284 women with pathological and physiological pregnancy. Results No differences in distribution of genotype and allelic frequencies of studied polymorphisms were found. GA genotype of RAGE 557 G/A polymorphism (known as Gly82Ser) is associated with lower sRAGE serum levels in healthy pregnant women compared to GG genotype (483 ± 104 vs. 692 ± 262 pg/mL, p = 0.008). sRAGE correlates negatively with ALT in patients with pregnancy intrahepatic cholestasis (r = − 0.536, p = 0.05). Conclusions We did not show any association of RAGE and glyoxalase I gene polymorphisms with pathological pregnancy, however further studies are needed to confirm the results.
