We have previously reported, in separate and combined analyses of GEM and the Western Australia Melanoma Health Study (WAMHS), the associations of IRF4 rs12203592, CCND1 rs11263498, and MX2 rs45430 with Breslow thickness [45] and IRF4 rs12203592 with melanoma-specific survival among first-order primary melanoma patients [46]. This evidence concerns the gene CCND1 and melanoma.
