To gain insight into profile of CWF19L1 in glioma samples, we employed Chinese glioma genome atlas (CGGA) database data (100 selected genes) for cluster analysis and found that CWF19L1 had higher levels of expression in proneural glioma than the other three GBM subtypes (classic, mesenchymal, nerve), because the proneural glioma has a good prognosis.17 The gene discussed is CWF19L1; the disease is central nervous system cancer.
