The importance of platform annotation in interpreting microarray data
The lancet oncology, 2010•thelancet.com
Weigelt and colleagues 1 recently compared three methods for classifying breast cancers
into molecular subtypes. Aside from an obvious question of whether they should have
centred each gene, an issue previously discussed in the context of classifying breast-cancer
subtypes, 2 there is concern that insufficient attention has been paid to the annotation of
probes on the microarray platforms that were used. We review the PAM50 (pediction
analysis of microarrays 50 gene set) 3 SSP (single sample predictor), as applied to the …
