The KIT mutations were located in the activation loop of the KIT protein tyrosine kinase 2 (n = 19), the juxtamembrane domain (n = 6), and the protein tyrosine kinase 1 domain (n = 1), resembling those previously described in TGCTs (Litchfield et al., 2015) and intracranial germ cell tumors (Wang et al., 2014) (Figure S2D). This evidence concerns the gene LTK and germ cell tumor.
