A gene that is known for its ability to repair DNA appears to instead cause breast cancer on mutation a new study has found.The gene GT198 whether mutated by genetics and/or environmental factors has strong potential as both as a way to diagnose breast cancer early and as a new treatment target said corresponding author Dr. Lan Ko from the Augusta University. Mutations of the gene are known to be present in both early onset breast and ovarian cancer. Now scientists have shown that the stem or progenitor cells which should ultimately make healthy breast tissue can also have GT198
