Study Description

Medulloblastoma is a heterogenous disease made up of at least four distinct subtypes of disease which appear to exploit and disrupt naturally occurring developmental pathways of cellular growth and hindbrain development. To better understand the driver mutations of this disease, we performed whole genome sequencing of 37 medulloblastomas and the corresponding normal DNA of the 37 affected children treated at St. Jude Children's Research Hospital. We have found several novel mutations which appear subtype specific. These mutations were checked for frequency in a separate tumor cohort of 56 children with medulloblastoma, also treated on the St. Jude Medulloblastoma 2003 trial, and were tested in several animal models of medulloblastoma for proof of oncogenic potential.

Study Inclusion/Exclusion Criteria

Cases of medulloblastoma treated at St. Jude Children's Hospital - St. Jude Medulloblastoma 2003 trial (SJMB03) with central pathology review confirming the diagnosis of medulloblastoma. The cases in this cohort have had whole genome sequencing of tumor and normal DNA performed. Cases were selected that had appropriate consent for genetic studies, and suitable material for sequencing (high purity tumor populations and available normal DNA).
