Researchers Find Unborn Babies Use Paternal Gene to Manipulate Mother’s Metabolism

Unborn babies utilize a paternal gene to manipulate their mother’s metabolism, ensuring they receive more nutrients during pregnancy, according to a study from the University of Cambridge. Researchers found that the gene, called Igf2, is inherited from the father and triggers a maternal-fetal tug of war over resources, redirecting nutrients to the fetus. Babies with Igf2 gene defects can experience abnormal growth, which can impact their health in later life. The findings could help develop strategies to support better health outcomes for both mothers and babies.
