In contrast, important CpG sites in the PWWP domain containing 3A, DNA repair factor (PWWP3A, commonly known as MUM1) gene locus for the prediction of MC high-grade neuroepithelial tumor with MN1 alteration (HGNET-MN1) were located in the gene body. This evidence concerns the gene PWWP3A and neuroepithelial neoplasm.
