ANN ARBOR, Mich. — Researchers in a multicenter international study have identified a new gene that, if mutated, may increase a woman’s risk of breast cancer by more than a third.Further, the researchers found that the gene, HMMR, interacts with the well-known breast cancer gene BRCA1. Alternations in either gene cause genetic instability and interfere with cell division, which could be a path to breast cancer developing. This leads researchers to not just a single gene, but a pathway that may be a potential target for treating or detecting breast cancer.
