The 10q22 chromosomal region with genomic linkage to pre-eclampsia in Dutch females shows a parent-of-origin effect with maternal transmission of the Y153H susceptibility allele of the STOX1 gene.
By using complementary in vitro and ex vivo approaches, we show that the risk allele (Y153H) of the pre-eclampsia susceptibility gene STOX1 negatively regulates trophoblast invasion by upregulation of the cell-cell adhesion protein alpha-T-catenin (CTNNA3).
