In PLOS One, researchers from Georgetown University and elsewhere describe a set of frequently mutated and/or copy number altered genes associated with poor breast cancer outcomes. The team profiled ductal carcinoma in situ samples and took advantage of genomic data on infiltrating ductal carcinoma cases from the Cancer Genome Atlas, looking at the prevalence of cases involving loss or low levels of SYK — a gene suspected of contributing to immunity and cancer risk.
