What was measured

Gene alterations, which include single nucleotide variants (SNPs), amplifications, deletions, translocations, indels, and germline alterations are shown for specific genes of interest in the results table.

Analysis population: Eligible medulloblastoma patients (n=81) were included in these analyses. Not all patients had data available for each gene.

Groups in this outcome

Low-Risk Group

Medulloblastoma patients \<3 years of age; histological diagnosis of desmoplastic nodular (DN)/medulloblastoma with extensive nodularity (MBEN); no evidence of metastatic disease (M0); and a surgical gross total resection (GTR) or near total resection (NTR) defined as residual tumor or imaging abnormality (not definite for residual tumor) with a size of less than 1 cm\^2 on post-op computed tomography (CT) or magnetic resonance imaging (MRI) \[R0\])

Intermediate-Risk Group

Medulloblastoma patients \<3 years of age, M0, and either R0 resection with any other medullo histology other than DN/MBEN (i.e., classic or large cell anaplastic (LCA)), or with a subtotal resection (with a residual tumor or imaging abnormality with a size of \>1 cm\^2 on post-op imaging (R+), and DN/MBEN). Children 3-5 years of age were also included in this group High Risk

High-Risk Group

Medulloblastoma patients \<3 years of age with evidence of metastatic disease
