Figure 4 presents the protein-protein interaction network of all ALS-associated genes (ATG16L2, SCFD1, VAC15, VEGFA, KEAP1, KIF5A, FIG4, TUBA4A, SIGMAR1, SETX, ANXA11, HNRNPL, NEK1, C9orf72, VCP, RPSA, ATP5B, and SOD1) together with the predicted kinases (AKT1, CDK1, CDK2, CDK4, DNAPK, MAPK14, and ERK2) and transcription factors (MYC, RELA, ZMIZ1, ESR1 EGR1, YY1, TRIM28, TAF7, CHD1, and FOXA2) visualized with k-mean clustering into seven clusters. The gene discussed is FIG4; the disease is amyotrophic lateral sclerosis.
