Methylation signature of pineoblastoma, pineal gland, and PPTID. Pediatric pineoblastomas form a distinct cluster that is separated from normal pineal gland and pineal parenchymal tumor of intermediate differentiation (PPTID). However, adult pineoblastomas cluster with PPTID (PB3 and PB8) as well as the normal pineal gland group (PB23), although analyzed tissues were confirmed as pineoblastoma, suggesting that methylation signature reflects origin of adult pineoblastomas from a normal pineal gland or a lower grade precursor lesion
