MITF and melanoma: Visualization of structural alterations of the DGAT1 gene in the Cancer Genome Atlas firehose legacy cutaneous melanoma dataset using cBioPortal revealed significant focal amplification (as defined by the stringent GISTIC 2.0 algorithm) in up to 7% of melanoma cases with available copy number variation (CNV) data (Figure 1E), comparable to other recognized melanoma oncogenes (namely CCND1, KIT, CDK4, MITF, TERT, and MDM2).
