Scientists have created a complete map showing how hundreds of possible mutations in a key cancer gene influence tumor growth. The study focused on CTNNB1, a gene that produces the protein β-catenin, ...

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, ...

Experiments from the 1940s established a key tenet of genetics—mutagenesis occurs randomly across the genome. New research, however, suggests that mutations may be less random than originally thought.
