HER2 is a proto-oncogene that encodes an 185 k Datrans membrane receptor tyrosine kinase which exhibits extensive homology to epidermal growth factor receptor (EGFR) .HER2 is also known as the neu and cerbB2 proto-oncogene.ER2 is a proto-oncogene that encodes an 185 k Datrans membrane receptor tyrosine kinase which exhibits extensive homology to epidermal growth factor receptor (EGFR) .
1 HER2 positivity is indicated if there are more than six copies of the HER2 gene per cell or if more than 2.2 HER2 genes are found for each copy of chromosome 17. 2  The latter is termed the HER2 chromosome enumeration probe 17 or the CEP17 ratio.
