BRCA1 and breast carcinoma: For example, ddPCR has been successfully applied to detect HER2 CNVs in formalin-fixed, paraffin-embedded (FFPE) breast carcinoma tissue, BRCA1 CNVs in whole blood-derived breast and ovarian cancers, MYCN amplification in neuroblastoma FFPE samples, MET CNVs in FFPE gestic cancer, and hepatocellular carcinoma.
