OBJECTIVE: To evaluate if variants in the genes CYP1A1 (T3801C and A4889G), CYP1B1 (G119T), GSTM1 (indel) and GSTT1 (indel) are associated with breast cancer (BC) among Mexican women. MATERIALS AND METHODS: 952 incident cases with histologically confirmed BC were matched by age (+/- 5 years) and zone of residence with 998 healthy population controls. Genetic variants in genes CYP1A1, CYP1B1, GSTM1 and GSTT1were genotyped by allelic discrimination and multiplex PCR. In a subsample of women, 105 markers for ancestry were determined. RESULTS: An increased BC risk, independent of other BC risk factors, was observed among carriers of CYP1B1 G119T genotype (T/T vs. G/G: OR=1.9; 95%CI 1.4-2.5). CONCLUSION: Our results support the existence of genetic susceptibility for BC conferred by CYP1B1 G119T variant among Mexican women.
