NLRP1 L155H polymorphism is a risk factor for preeclampsia development

Abstract

Problem: Augmented levels of IL-1 ss have been pointed out as an important pathogenic factor for preeclampsia development. Inflammasome is the cytoplasmic complex responsible for pro-IL1 ss cleavage and IL-1 ss secretion. Aim of the study was to evaluate the association between polymorphisms in inflammasome'genes and preeclampsia. Method of study: Selected polymorphisms in inflammasome genes (NLRP1, NLRP3, CARD8, and IL1B) were analyzed in 286 Brazilian women with and 309 without preeclampsia. Results and Conlclusions: The NLRP1 variant rs12150220 (L155H) was associated with the development of preeclampsia (OR=1.58), suggesting a role of this inflammasome receptor in the pathogenesis of this multifactorial disorder.
