Moreover, in the non-astrocytoma subgroup, two haploblocks including ATM (rs228599, rs664143, rs170548, rs3092993, and rs3092992) and XRCC4 (rs7721416 and rs2662242) with, respectively, five and three haplotypes with frequency of > 1% were observed; nevertheless, in none of these haploblocks, the distribution of haplotypes was significantly different between patients and controls (χ2 = 1.92, df = 4, p = 0.751 and χ2 = 2.98, df = 2, p = 0.226, respectively). The gene discussed is XRCC4; the disease is astrocytoma (excluding glioblastoma).
