Pregnancy loss is common in humans, but maternal genetic factors modulating its incidence are largely unknown. In a meta-analysis of genome-wide association studies, researchers identified a genetic variant that seems to increase risk of pregnancy loss by dysregulating meiotic recombination between homologous chromosomes during egg formation.
