Finding could explain the human sex ration that slightly favors males over females.

In mice, the failed epigenetic suppression of Xist leads to fetal developmental abnormalities and miscarriage. Knocking out the Xist gene greatly reduced prenatal death. The findings have implications for understanding infertility and developing new treatments to prevent miscarriage.
