Expression arrays from 65 of the 183 tumours analysed were used to determine gene expression levels of genes with recurrent promoter and 3' and 5' UTR mutations. A total of 32 samples is available at GSE54467; the remaining 33 samples are submitted here. The 27 primary melanoma samples (AJCC stage II) were assayed using the HumanHT-12 v4 Expression BeadChip (Illumina® Inc., San Diego, CA, USA; Catalog IDs: BD-103-0204, BD-103-0604). The remaining 6 metastatic (AJCC stage IV) samples were assayed using the HumanWG-6 v3 Expression BeadChip ((Illumina® Inc., San Diego, CA, USA; Catalog IDs: BD-101-0203, BD-101-0603). NEQC normalisation (default parameters) was separately applied to each of the AJCC stage II and IV datasets (http://nar.oxfordjournals.org/content/38/22/e204). Probes for which there were no samples with a detection p-value of less than 0.01 were removed.
