EGFR and malignant peripheral nerve sheath tumor: Cerebellar degeneration-related protein 1 (CDR1as) is known to be associated with miR-7 [35], which can regulate the occurrence of several tumors including lung cancer [36], gastric cancer [37], and malignant Schwannoma by inhibiting the expression of its target genes, such as EGFR [38,39], insulin-like growth factor receptor (IGF1R) [37], and activated Cdc42-associated tyrosine kinase 1 (ACK1) [38].
