KAT6B and glioma: In addition to the gene expression variations, we also observed a slightly higher rate of somatic mutations in these histone acetylation regulators in the TCGA gliomas compared to other epigenetic categories; KAT6B was the only gene containing the same mutation (T1203Rfs*21) at a single position in more than one case (four cases), but no mutated genes were found in “histone phosphorylation”, “reader”, or “chromatin remodeling” categories (Figure 1B).
