IL17A and juvenile Huntington disease: The results of KEGG pathway annotation analysis showed that DEGs are mainly involved in 10 relevant information pathways, including the IL-17 signaling pathway, steroid hormone biosynthesis, cAMP signaling pathway, oxytocin signaling pathway, riboflavin metabolism, thiamine metabolism, purine metabolism, starch and sucrose metabolism, fluid shear stress and atherosclerosis, and Huntington’s disease (Figure 4C).
