“…Interestingly, many of the gene loci associated with susceptibility have already been causally linked to the pathogenesis of cHL in targeted studies, by altered expression levels or specific mutations (1,74,75). We recently performed a whole-exome sequencing (WES) study of five cHL cell lines and found mutations in several of the associated genes, including HLA, B2M, NFKBIA, STAT3, and STAT6 (76), again indicating that antigen presentation and the IL13 pathway are critically important in cHL pathogenesis.…”
