Expand Collapse EGFR  - General Description The EGFR gene encodes for a cell-surface protein known as the epidermal growth factor receptor, which is found in many normal epithelial tissues such as the skin and hair follicles. When epidermal growth factor ligand bind to EGFR, they activate several different cell signaling pathways that control various cell functions, including cell growth and proliferation. Mutations in EGFR can lead to unregulated activation of the protein. These types of activating mutations are often found in NSCLC (non-small cell lung cancer), glioblastoma and head and neck squamous cell carcinoma. Sometimes, excess EGFR protein is produced due to the presence of too many copies of the EGFR gene, leading to excessive cell division and growth in the presence of epidermal growth factor. Among the human cancers in which EGFR overabundance is present are cancers of the head and neck (squamous cell), colon, rectum, lung (NSCLC), central nervous system (glioblastoma), pancreas and breast (HER2-positive metastatic). Blocking EGFR in tumors may keep cancer cells from growing. The FDA has approved several therapies that target EGFR in one or more cancers. Testing for genetic alterations of EGFR is available at the MGH genetics lab. Treatment for EGFR-mutant tumors, along with clinical trials testing new drugs for the treatment of EGFR-mutant tumors are available at the MGH Cancer Center. Tumor mutation profiling performed clinically at the MGH Cancer Center has indicated that EGFR mutations occur primarily in lung cancer (~15%), but also in a minor subset of gastric (2%), brain (1%) and pancreatic (1%) cancers.

Expand Collapse Exon 19 Deletion  in EGFR
The EGFR exon 19 mutation is an 11-18 base pair deletion in the portion of the EGFR gene that codes for the ATP binding site, an important portion of the receptor for proper function. The missing base pairs occur in such a way that they are "in-frame", meaning that they can be transcribed or read from the DNA to form a protein that is abnormal (missing the portion of the protein coded by the deletion in the DNA). The abnormal EGFR (exon 19 deletion) protein is constantly active, sending "grow" signals even in the absence of growth ligands. This constant signal to grow and divide contributes to the development of cancer.
