Épigénétique de la prééclampsie
Preeclampsia is a pregnancy-associated disease with maternal outcome but placental origin. Genome wide linkage analysis revealed that preeclampsia segregates with at least four different susceptibility loci: 2p12 (Iceland), 2p25 (Finland), 9p13 (Finland) and 10q22 (the Netherlands). The Dutch locus...
