First, we evaluated the expression of KIF genes in 33 tumor types (Figure 1A), of which the 5 genes with the highest expression were KIF5B, KIF1C, KIF1B, KIF3B, and KIF22, while the 5 genes with the lowest expression were KIF5A, KIF4B, KIF6, KIF1A, and KIF17. The gene discussed is KIF17; the disease is neoplasm.
