Additional Information	Clinical Significance: HER2, a member of the epidermal growth factor receptor family, is a transmembrane protein with tyrosine kinase activity. Gene amplification and protein overexpression of HER2 have been found in a variety of tumors. This test provides HER2 amplification status to aid in determining anti-HER2 targeted therapies for patients. Scoring is performed using the following: HER2 (Other) with Breast scoring uses the 2018 CAP/ASCO guidelines for breast cancer for HER2 evaluation. Breast scoring is recommended for indications such as endometrium cancer, salivary duct carcinoma, serous carcinoma, and ovarian cancer as well as other clinical indications without consensus guidelines. HER2 (Other) with Gastric scoring uses the 2016 CAP/ASCP/ASCO consensus guidelines for gastric/gastroesophageal adenocarcinoma for HER2 evaluation.
