I would like to know if someone is aware of a web application that would give indication or patient samples in which a given gene is found to be amplified.
For instance at the Sanger there is the CONAN tool where you can enter an HUGO gene name and it gives you all the human cancer cell lines where you gene is in a genomic region with a High Level Amplification (>7).
What is it that you need the tool to be able to do that CONAN doesn't? To me it sounds like you answered your own question, but I have probably misunderstood something.
Actually CONAN is an instance related to cancer cell lines. I am looking for the same kind of tool but applied to patient samples.
