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.
