Data from genome-wide association studies of glioma have identified single nucleotide polymorphisms (SNP) associated with altered risk of IDH-mutated glioma, including rs55705857 in 8q24.21, rs4295627 in CCDC26, and rs498872 in PHLDB1 [23, 24], and in a recent case-control study of 285 gliomas, 316 healthy controls, and 531 other types of cancers, the authors showed that SNP rs55705857 was strongly associated with altered risk of IDH-mutant glioma, but not with other cancers [23]. Here, CCDC26 is linked to glioma.
