Additionally, the aberrant expression and function of KIF4A have been implicated in the pathogenesis and progression of a variety of solid tumours, including insulinoma [82], pleural mesothelioma (PM) [112], meningioma [113], skin cutaneous melanoma (SKCM) [114], and Ewing sarcoma (ES) [115]. The gene discussed is KIF4A; the disease is Ewing sarcoma.
