  • Assessment of genetic polymorphisms are described in Methods. Percentages are given in parentheses. Statistical significance of differences between patient and control group was assessed with the chi-square test.

  • EPHX, epoxide hydrolase; Tyr, tyrosine; His, histidine; Arg, arginine.

  • 2-150 p<0.01 pre-eclampsia versus controls.
