Human Reproduction and Development


The research activities of my group are aimed at understanding the molecular mechanisms responsible for hydatidiform mole and reproductive wastage in humans. A hydatidiform mole is an abnormal human pregnancy with no embryo. The sporadic form of this condition occurs in 1 in every 1500 pregnancies in Western countries, but at a higher frequency in other parts of the World. By analyzing rare familial cases, we mapped and identified a maternal defective gene, NLRP7, responsible for this condition. NLRP7 is a member of the CATERPILLER protein family with roles in auto-inflammation, pathogen-induced inflammation, and apoptosis. Our current research addresses the roles of NLRP7 in moles and recurrent reproductive wastage and the identification of additional genes for these conditions.
