PE is associated with markers of autoimmunity, including anti-β2 glycoprotein-I (ab2GPI); anticardiolipin antibodies (aCL); lupus anticoagulant (LA); β1, β2, and α1 adrenoreceptors; prothrombin; endothelin-1 receptor type A (ETA-AA); and Angiotensin II receptor type 1(AT1-AA) antibodies [66,67] as well as antibodies with different specificity than AT1-AA [68]. This evidence concerns the gene AGTR1 and Autoimmunity.
