Polymorphisms of the gamma-glutamyl hydrolase gene and risk of relapse to acute lymphoblastic leukemia in Mexico.
This study evaluated the association of -401C/T and +452C/T polymorphisms of gamma-glutamyl hydrolase and the risk of relapse to acute lymphoblastic leukemia. Genotyping was performed in 70 children with acute lymphoblastic leukemia and 140 healthy children. An association between the -401C/T polymorphism and the risk of relapse was found (p=0.028), patients with the -401T/T genotype have 10.83 (95% CI 1.30-90.14) more chance of a relapse of leukemia. No association was found between the +452C/T polymorphism and the risk of relapse. Therefore, our investigation suggests that the -401C/T polymorphism in the gamma-glutamyl hydrolase may be a factor involved in the generation of relapse to disease in patients with ALL.
