IKBKG and preeclampsia: Because we hypothesized that predisposition to preeclampsia development may be related to simultaneous occurrence of the same variant in maternal and fetal NEMO gene, further analysis was performed to check whether there is a statistical difference between the study and control subgroups consisting of maternal and fetal cases in whose genomes we observed only an AA genotype (mothers and daughters)/A allele (sons) for the IKBKG:c.*368C>A variant or only a TT genotype (mothers and daughters)/T allele (sons) for the IKBKG:c.*402C>T variant.
