Human epidermal growth factor receptor 2 (HER2) is a proto-oncogene encoding a transmembrane glycoprotein with tyrosine kinase activity. The amplification and overexpression of this gene have been observed in breast and ovarian cancers and are associated with the response of breast cancers to chemotherapy. A single nucleotide polymorphism (SNP) at codon 655 resulting in a valine to isoleucine change (Val655Ile) was reported in the Journal
