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.
