Another use is for genetic analysis including gene expression analysis of tumor biomarkers such as HER2/E-cadherin by qRT-PCR, and mutation analysis of oncogenes/suppressor oncogenes such as EGFR/KRAS by PCR-based whole genome amplification (WGA) and subsequent direct sequencing (Figures 7C–7E). The gene discussed is EGFR; the disease is neoplasm.
