This allowed to classify the patients into 4 groups, two IDH mutation and two 1p/19q codeletion statuses, that were subsequently used to perform the two binary classification tasks: IDH-mutant (n = 24) versus IDH-wildtype (n = 33), 1p/19q codeleted (n = 12) versus non-codeleted (n = 45) gliomas. The gene discussed is IDH1; the disease is glioma.
