GISTIC2 comparison nominated amplifications at 22q13.2 (containing EP300), which was exclusively present in acral melanoma (q = 0.0016) and 3p13 (containing MITF), exclusive to mucosal melanoma (q = 0.22), but these differences did not reach formal levels of significance (P > 0.05). This evidence concerns the gene MITF and mucosal melanoma.
