Methylation Class Description

The methylation class “diffuse leptomeningeal glioneuronal tumor” is mainly comprised of tumors with the histological diagnosis of diffuse leptomeningeal glioneuronal tumor. The most frequent initial location is spinal. In the course of the disease dissemination along the leptomeninges is frequent. Supratentorial tumor nodule formation is also possible. Median age is 13 years (range 5 to 39). Typical copy number changes are a loss of 1p (>90%) and occasionally a combined loss of 1p/19q (40%) co-occurring with BRAF duplication (BRAF fusion). IDH1/2 mutations are not observed.

TSNE Clustering

Copy Number Variation Profile

Depiction of chromosome 1 to 22 (and X/Y if automatic prediction was successful). Gains/amplifications represent positive, losses negative deviations from the baseline. 29 brain tumor relevant gene regions are highlighted for easier assessment.

MGMT methylation analysis of glioblastoma on the Infinium methylation BeadChip identifies two distinct CpG regions associated with gene silencing and outcome, yielding a prediction model for comparisons across datasets, tumor grades, and CIMP-status.

This result alone cannot be used for diagnosis of cancer and has to be interpreted in the context of all available clinical and pathological information. This test was developed, and its performance characteristics determined, by the NYU Molecular Diagnostic Pathology. It has not been cleared or approved by the U.S. Food and Drug Administration (FDA). The FDA has determined that such clearance is not necessary.
