Extrapolating from our previous results obtained with TCGA data for human melanoma [39], we expected to observe an association between a high proportion of IGHG1/IGH and long survival, where IGH is a sum of the expression of the IGHA1, IGHA2, IGHG1, IGHG2, IGHG3, IGHG4, IGHM, IGHD and IGHE genes. This evidence concerns the gene IGHG3 and melanoma.
