Graphical overview of chromosomal aberrations in SCCs and AKs. Idiograms summarizing chromosomal aberrations in SCCs (A) and AKs (B) compared to the patient matched normal control. LOH events are shown to the left of the chromosomes in either red (physical loss) or blue (copy-neutral LOH (cnLOH)). Gains are indicated on the right of the chromosomes in green. Dotted lines represent aberrations that were not present in all tumor cells of a sample.
