Meet the luckiest people on Earth — individuals carrying a rare genetic mutation that prevents wrinkles from forming even as they age well into their 80s. These genetic lottery winners have provided ...

A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

A microscopic flaw in the brain’s cellular scaffolding can shape brain size for life.

Researchers used miniature human brains grown in the lab to uncover why certain genetic mutations lead to abnormally small brains. Changes in actin disrupted the orientation of early brain cell ...

What Is the MTHFR Gene Mutation? The MTHFR gene mutation is a variation in the MTHFR gene. This gene normally tells your body how to make the MTHFR protein. You need this protein to process folate, ...
