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. Here, KCNIP2 is linked to astrocytoma (excluding glioblastoma).
