Notably, synonymous variants found in this tumor were detected in other tumors, such as APC (rs41115) variant in MPE [31], FGFR3 (rs7688609), PDGFRA (rs1873778), and RET (rs1800861) in anaplastic ependymoma Grade III tumor, a-CPP, and myxo-papillary ependymoma (MPE) tumors [20,22,23]. Here, RET is linked to neoplasm.
