Analysis of the SHAP values for the remaining genes (Supplementary Figure S2) revealed that increased expression of ZDHHC18, HDAC1, and TUBB6 enhances the probability of predicting astrocytoma, while elevated expression of TERT, TRIM67, NOG, KCNIP2, and KCNJ11 increases the probability of predicting oligodendroglioma. The gene discussed is NOG; the disease is oligodendroglioma.
