Researchers have identified inherited genetic variants that may predict the loss of one copy of a woman's two X chromosomes as she ages, a phenomenon known as mosaic loss of chromosome X, or mLOX.

How much of our lifespan is written in our genes, and how much is sitting on our plates? A new analysis suggests that while ...
