WebJul 27, 2016 · FISH HER2 positivity was based on the HER2/CEP17 ratio (> 2.2) and on the average gene copy numbers. Gene copy numbers of >6 and cluster formation (6 copies by smaller clusters and 12 copies by larger clusters) were also defined as positive status. HER2 equivocal status by FISH was defined as a HER2/CEP17 ratio of 1.8–2.2. WebHER2 is the more common name for the gene called ERBB2.
