DSC3 and neoplasm: Tumor samples of Inserm series were predicted in 2 and 4 subtypes molecular classification using a predictor based on nine genes: ADAM19, ETS1, and PDCD1LG2 for C1 and C2; CLDN1, DSC3, and SLC24A3 for C1A and C1B; CHL1, ECM2, and PTPN13 for C2A and C2B subtype prediction (Fig. S8).
