Discovery of genes linked to preterm birth in landmark study


A massive international DNA analysis of pregnant women has identified for the first time six gene regions that influence the length of pregnancy and the timing of birth. The findings may lead to new ways to prevent preterm birth and its consequences — the leading cause of death among children under age 5 worldwide.
