HER1 gene
A gene that makes a protein called epidermal growth factor receptor (EGFR), which is involved in cell growth and cell survival. Mutated (changed) forms of the HER1 gene and protein have been found in some types of cancer, including non-small cell lung cancer. These changes may cause cancer cells to grow and spread in the body. Checking for changes in the HER1 gene in tumor tissue may help plan cancer treatment. Also called EGFR gene, epidermal growth factor receptor gene, and ERBB1 gene.
