NCIt synonyms : HER2/CEP17 Ratio; HER2/CEP17 Dual-Probe Fluorescence In Situ Hybridization Ratio Assay; HER2/CEP17 Ratio Assay; HER2/CEP17 Ratio Measurement; HER2/CEP17 Fluorescence In Situ Hybridization Ratio Assay; ERBB2/CEP17 FISH Ratio Assay;
NCIt related terms : ERBB2 gene copy number/Chromosome 17 copy number in Tissue by FISH;
NCIt definition : A dual-probe fluorescent in situ hybridization-based assay used to determine the ratio
of signal intensity present in a sample for two probes, one that is specific for ERBB2
(HER2) expression and one that is specific for chromosome 17 centromeric sequences
(CEP17). Since the HER2 gene is present on chromosome 17, ratios greater than 1 indicate
gene amplification or mRNA overexpression for HER2.;
