Many, if not most, studies of FOXO1-PAX fusion in rhabdomyosarcoma combine these two fusion subtypes, and few studies have PAX3 may differ from PAX7. Here, we show that PAX3 vs PAX7 differences may be widespread to gene co-expression with many of genes having higher expression levels in PAX7 (Figure 3). This evidence concerns the gene FOXO1 and rhabdomyosarcoma.
