Copy number aberrations of meningiomas. Array-comparative genomic hybridization data derived from 23 primary meningioma tumors were processed to identify loss (grey boxes), gain (black boxes) or both loss and gain (patterned boxes) of part or all of a given chromosomal arm. Each column represents one case and each row represents the indicated chromosomal arm. The WHO Grades and the molecular subgroups of the individual cases are indicated below the case numbers. The asterisk refers to the Grade 2 meningioma with a unique expression pattern.
