I would echo these sentiments.
@tres - how exactly does your data come back to you? Do you get the full dataset from the sequencing run back, or just their analysis of it? If it’s the former, how are you going to analyse it? The latter - how are you interpreting their analysis? Genomics is very rarely totally black and white, especially in terms of cancer genes. Lots of unknowns still to be discovered.
Those who are paranoid are very right to be, especially if you’re going through a private company. Read the terms very carefully.
