DMD and meningioma: While chromosomal losses were more frequent than gains, 5 tumors showed a CNV profile characterized by gains of 5 or more whole chromosomes, including chromosome 5 (Supplementary Figure S1), a copy number profile that has been described in angiomatous meningioma.28 One patient harbored a segmental loss of one copy of DMD on Xp21.2, which has been associated with shorter survival in meningioma.29 This patient is alive without recurrence after 20 years of follow-up.
