K-ras gene  listen  (... jeen)

  A gene that may cause cancer when it is mutated (changed). The K-ras gene makes the KRAS protein, which is involved in cell signaling pathways, cell growth, and apoptosis (cell death). Agents that block the activity of the mutated K-ras gene or its protein may stop the growth of cancer. Also called Kras gene.
