We found that 17 genes were enriched in the Huntington’s disease (hsa05016) KEGG pathway; among them, 11 genes (TRAF2, MAPK8, BAX, CASP9, SP1, BBC3, CASP3, TP53, APAF1, CYCS, and CASP8) were shared between Huntington’s disease (hsa05016) and pathways in cancer (hsa05200) (Figure 1). Here, CASP9 is linked to cancer.
