WEDNESDAY, Feb. 22 (HealthDay News) -- Scientists have identified a new gene mutation linked to breast cancer.
The mutation affects the ability of the Abraxas protein to enter the nucleus and bind to sites adjacent to damaged DNA. This leads to genetic alterations that increase breast cancer risk, Roger Greenberg, an associate professor of cancer biology at the Perelman School of Medicine at the University of Pennsylvania, said in a university news release.
The findings, published Feb. 22 in the journal Science Translational Medicine, appears to establish Abraxas as a breast cancer-susceptibility gene, according to the researchers.
It has been known that BRCA genes do not act alone in causing breast cancer, but it has proven difficult for scientists to identify other culprits. In time, this Abraxas mutation may be added to the list of 14 mutations for which women in families with a history of breast cancer can be tested, the researchers said.
