While several publications describe increasing GAM levels depending on the WHO grade of diffuse gliomas 15, we merely detected nonsignificant trends of increasing levels of Iba1‐ and CD68‐positive GAMs (both classical pan‐M/M marker) with increasing WHO grades II to IV in the distinct molecular subclasses of IDH1R132H‐mutant and ‐non‐mutant diffuse astrocytomas. The gene discussed is AIF1; the disease is diffuse astrocytoma.
