Hi all,

I was wondering if anyone has attempted using RNA-Seq for applications like prognostic or diagnostic classifier model generation? There are numerous examples of this being done with microarrays (e.g. Mammaprint) however I am not aware of any NGS work in the field.

Any help appreciated.

didn't we cover this?

What would be the conceptual difference between doing it for RNA-seq-derived as opposed to microarray-derived expression data?

Jeremy - no I don't think so. My previous question referred to both classifiers and association and I don't believe I got any answer on the classification.

Mikael - I don't know myself! I believe the concept must be pretty much the same but I'm guessing there have to be some technology-specific factors that would complicate matters. I'm trying to determine if anyone has actually attempted it.

It depends:

RNA-Seq signatures in publications: Lots. Here are some off the top of my head: (algorithm applied to microarray and RNA-Seq data)

RNA-Seq diagnostics in clinic: Probably none. It takes several years to get FDA approval for a diagnostic. Plus, identification of a signature via RNA-Seq doesn't mean final application to use RNA-Seq. For example, I believe most microarray-based signatures in papers that actually made it to the clinic were implemented via qPCR for only the genes in the signature.
