It is important to point out that MMP9 and SEPT7 were carrying a deletion variant with a feature of a truncation in each GBM sample (A, B, C, E, Supplementary Figure 1) implying a disruption of the gene with very likely loss of gene expression, as we indeed observe in the RNAseq data (Figure 1G). The gene discussed is SEPTIN7; the disease is glioblastoma.
