According to the KEGG pathway analysis results of KIT, we found that KIT was significantly associated with oxidative phosphorylation, fatty acid metabolism, peroxisome proliferator-activated receptors (PPARs) signaling pathway, adipocytokine signaling pathway, glutathione metabolism, Notch signaling pathway, P53 signaling pathway and primary immunodeficiency. This evidence concerns the gene KIT and inborn error of immunity.
