As the methyl group is ... WebMethylation of the MGMT gene promoter has been observed in approximately 50% of grade IV gliomas, commonly referred to as glioblastoma multiforme (GBM) [1]. Remarkably, in cases with monosomy of chromosome 10, a common event in GBMs, methylation of the remaining allele completely blocks MGMT-mediated DNA repair [2].
