XRCC4 and astrocytoma (excluding glioblastoma): In addition, the stratified analyses showed 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 (pREC=0.021, pREC=0.001, pDOM=0.041, and pREC=0.027, respectively) as well as a decreased risk of this subtype associated with the A allele of XRCC4 rs7721416 and the C allele of XRCC4 rs2662242 (DNA repair pathway) (pREC=0.032 and pREC=0.024, respectively) (Tables 3 and 4).
