Association Study of Xenobiotic Detoxication and Repair Genes with Malignant Brain Tumors in Children

This study presents the results of research on DNA polymorphism in children with malignant brain tumors (172 patients, 183 in the control group).

Sumario:This study presents the results of research on DNA polymorphism in children with malignant brain tumors (172 patients, 183 in the control group). Genotyping was performed using an allele-specific tetraprimer reaction for the genes of the first (CYP1A1 (2 sites)) and second phases of xenobiotic detoxication (GSTM1, GSTT1, GSTP1, GSTM3), DNA repair genesXRCC1, XPD(2 sites),OGG1, as well asNOS1andMTHFR.The increased risk of disease is associated with a minor variant ofCYP1A1(606G) (p = 0.009; OR = 1.50) and a deletion variant ofGSTT1, (p = 0.013, OR = 1.96). Maximum disease risk was observed in carriers of double deletions inGSTT1-GSTM1(p = 0.017, OR = 2.42). The obtained results are discussed in reference to literary data on the risk of malignant brain tumor formation in children and adults.
