MDM2 and melanoma: Comparison of genes amplified in our samples with published gene lists from two large melanoma studies (Stark and Hayward 2007; Gast et al., 2010) while revealing very little overlap (see Fig. 4) did identify BRAF, MDM2, and NRAS, genes known to be important in melanoma [5], [17], [23], [24], [25], [26], [27], [28], [29].
