Pan-cancer analyses using The Cancer Genome Atlas datasets revealed that the levels of SMARCD3 and DAB1 mRNA expression were not correlated (R = 0.17, P < 2.2 × 10–16), including no positive correlation in low-grade glioma and glioblastoma (R = −0.11, P = 0.0023) (Extended Data Fig. 4e,f). This evidence concerns the gene SMARCD3 and central nervous system cancer.
