Distribution of the clinical glioma samples by tumor type (World Health Organization grade) (n = 147). The majority of the collected formalin-fixed paraffin-embedded clinical samples meeting inclusion criteria for the IDH1/2 PCR test originated from patients with diagnosed primary glioblastoma, the most frequently diagnosed glioma subtype in clinical routine. The remaining samples originated from patients diagnosed with other histological forms, mainly astrocytomas. Samples were available for each diffuse glioma subtype.
