- Abstract
Determination of the presence of HER2 amplification by quantitative PCR has been challenging, in part due to chromosomal instability and identification of a robust a reference region. We assessed the potential of digital PCR for highly accurate assessment of DNA concentration with EFTUD2 as chromosome 17 reference probe. We assessed a HER2:EFTDU2 ratio by digital PCR assay in the microdissected DNA from 18 HER2 amplified and 58 HER2 non-amplified cancers. The HER2:EFTUD2 ratio had high concordance with conventionally defined HER2 status with a sensitivity of 100% (18/18) and a specificity of 98% (57/58). The HER2:EFTUD2 digital PCR assay has potential to accurately assess HER2 amplification status.
