Hras gene
(… jeen)
A gene that may cause cancer when it is mutated (changed). The Hras gene makes the HRAS protein, which is involved in cell signaling pathways, cell growth, and apoptosis (cell death). Agents that block the actions of the mutated Hras gene or its protein in cancer cells may stop the growth of cancer. Also called H-ras gene.
