IL13 and preeclampsia: Since genetic factors are believed to be involved in the development of preeclampsia, and existing data confirm the association of IL‐13 polymorphism with inflammatory states and disorders, e.g., association of SNP IL‐13 + 1923 C/T with asthma development [14], or association of IL13 rs20541 with significantly decreased susceptibility to renal cell carcinoma (a disease with immune predisposition) [15], our study aimed to analyze the possible impact of IL-13 gene polymorphism with the susceptibility to preeclampsia.
