We further compared mucosal melanoma from patients of European and Asian ancestry (n = 48 and 42; Additional file 2: Fig. S15E) and found that SF3B1 mutations were predominately observed in the former (22.9% vs. 2.4%), while SKP2 amplifications were more frequent in the latter (4.2% vs. 19%). The gene discussed is SKP2; the disease is melanoma.
