WebThe most common IDH1 mutation – accounting for approximately 90% of all IDH mutations – causes an amino acid change from arginine to histidine (R132H) in the active site of the enzyme 13. Besides IDH1 R132H, rarer … Weband SOX2, which are indicative of glial and neuronal cells, and negative for IDH1 R132H mutation-specific immunomarker, which is more common in low-grade, less aggressive, gliomas. There was loss of MLH1 and PMS2 expression, with retention of MSH2 and MSH6. As discussed below, MLH 1 promoter methylation was performed in gruppentherapie systemische therapie
