In addition, an increased risk of non-astrocytoma tumor subtype associated with the C alleles of EGFR rs9642393, EME1 rs12450550, and ATM rs170548, and the T allele of GLTSCR1 rs1035938 as well as a decreased risk of this subtype associated with the A allele of XRCC4 rs7721416 and the C allele of XRCC4 rs2662242 were detected. Here, XRCC4 is linked to astrocytoma (excluding glioblastoma).
