Women of Latin American descent, particularly those with indigenous ancestry, may carry a genetic variant that protects them from breast cancer.

Previous epidemiological studies have shown that Latinas seem to be less susceptible to developing breast cancer than women of other ethnicities. Now an international group of scientists, led by UCSF researchers, have identified the spot on the DNA sequence responsible for that protective effect.

The research is still a long way from making testing for the variant available. Scientists still have a lot more work to do to figure out what the variant means and exactly how it interacts with the body to reduce breast cancer risk.
