Research Focus
My research work is focused on the genetics of various forms of fetal loss. I started my career on the genetic causes of molar pregnancies, a particular form of abnormal human pregnancies with no embryos, and identified its first and major gene, NLRP7. I also linked this condition to mutations in two other genes, NLRP5 and PADI6. Recently, with my group, I identified three additional genes, MEI1, TOP6BL, and REC114, responsible for recurrent moles. While NLRP7 is responsible for diploid biparental molar pregnancies, those caused by defects in MEI1, TOP6BL, and REC114, are androgenetic. With my collaborators, I used a mouse model for one of the identified genes and modeled how androgenetic conceptions form and identified a novel meiotic abnormality at their origin. The work of my group contributed significantly to current understanding of recurrent moles and I am currently expanding my research interests to the genetics of recurrent miscarriages.
