NCI Definition: Neoplasms that are located in the pineal gland. These neoplasms arise either from pineal parenchymal cells (pineocytes), as do pineocytomas and the more aggressive pineoblastomas, or from other cell types, as do pineal astrocytic tumors (notably pilocytic astrocytomas) and germ cell tumors. Clinical symptoms include neuro-ophthalmologic dysfunction, changes in mental status, dysfunction of the brain stem, and hypothalamic-based endocrine abnormalities. [1]

Pineal region neoplasms most frequently harbor alterations in DICER1, ATRX, EPHB1, CDK12, and CBL [2].

Most Commonly Altered Genes in Pineal Region Neoplasm

DICER1 Mutation, EPHB1 V205E, EPHB1 Mutation, CDK12 P1091S, and CDK12 Mutation are the most common alterations in pineal region neoplasm [2].
