Colon core source genes.

There are five “core” source genes which appear in every minimal source covering of the colon samples. P(DNA) is the fraction of samples for which the indicated source gene is DNA-aberrant; P(DNA&downstreamRNA) is the fraction of samples for which the indicated source gene is DNA-aberrant and there exists an RNA-aberrant gene among its targets. P(downstreamRNA|DNA) is the fraction of the samples with the indicated source gene DNA-aberrant for which there exists some RNA-aberrant gene among its targets.
