Basal, H2O2-induced, and postrepair DNA damage; urinary 8-hydroxydeoxyguanosine level as a marker of oxidatively damaged DNA; and serum total antioxidant capacity were measured; XPD Lys751Gln, XRCC1 Arg399Gln, and XRCC1 Arg194Trp polymorphisms were analyzed in childhood acute lymphoblastic leukemia (ALL) survivors.
In this study, we investigated the possible association of X-ray repair cross-complimenting group 1 (XRCC1) Arg399Gln and Arg194Trp variants with the risk of incidence of childhood acute lymphoblastic leukemia (ALL) in Turkish population comprised of 190 healthy controls and 167 ALL patients.
However, the combined XRCC1 Arg194Trp/Trp194Trp variant genotypes were associated with increased risk for ALL in females (OR=5.47; 95% CI=1.49-20.10; p=0.008).
We examined the influence of the Arg194Trp, Arg280His, and Arg399Gln polymorphisms of XRCC1 (X-ray repair cross-complementing group 1) on the development of childhood acute lymphoblastic leukemia (ALL) in 120 ALL patients and 120 controls in Mexico.
We genotyped polymorphisms of X-ray repair cross-complimenting group 1 (XRCC1) codon 194 (Arg to Trp), 280 (Arg to His) and 399 (Arg to Gln), and xeroderma pigmentosum group D (XPD) codon 312 (Asp to Asn) and 715 (Lys to Gln) in 108 children with ALL and 317 healthy controls using PCR-RFLP method.
