The vast majority of such genes (554) were private to a single melanoma sample; seventy genes were shared by two samples; and only ten genes were shared by three melanomas: ADAMTSL1, ARMC4, DLL1, HSD17B3, LOC441177, OSTCL, PARK2, PLXDC2, SLC24A2 and ULBP3 (see Table S2). This evidence concerns the gene DLL1 and melanoma.
