Thirteen molecular traits have been previously linked with glioma risk and five were novel; HBEGF (5q31.3) expression and all glioma [OR 1.36 (95%CI 1.19–1.55); P = 4.41 × 10−6]; a CEP192 (18p11.21) splice isoform and glioblastoma [OR 4.40 (95%CI 2.28–8.48); P = 9.78 × 10−4]; a FAIM (3q22.3) splice isoform and all glioma [OR 2.72–3.43; P = 1.03 × 10−5 to 1.09 × 10−5]; a SLC8A1 (2p22.1) splice isoform and all glioma [OR 0.37 (95%CI 0.24–0.56; P = 5.72 × 10−6]; D2HGDH (2q37.3) protein and all glioma [OR 0.86 (95%CI 0.80–0.92); P = 5.94 × 10−6)]. Here, HBEGF is linked to glioblastoma.
