BMP4 expression showed a Proneural, G1 subtypes and IDH1 mutation preference. For each patient, TCGA and CGGA subtype were annotated as previously reported and listed in the upper part as well as the IDH1 mutation status, which was obtained from CGGA database. The positively and negatively correlated genes were showed in the lower part (marked pink and blue in the right, respectively). NA, not available.
