GSTM1, GSTT1 and GSTP1 were studied in chronic myeloid leukemia patients and controls to assess their role on disease risk and treatment response.
A trend toward significance was found for GSTP1 for a recessive model suggesting a potential association with the CML risk in Argentinean patients.
Patients carrying combined GSTM1-null/GSTP1-GG or GSTT1-null/GSTP1-GG genotypes were associated with CML susceptibility.
Patients with GSTM1 gene as well GSTP1-GG genotype were associated to treatment failure
This study highlights the identification of GST markers associated to CML susceptibility and treatment response.
