| Two members of the mu class of glutathione S transferase ( GST ) genes , GSTM 1 and GSTM 3 , have polymorphic alleles which have been associated with altered levels of GST mu protein expression and may be linked to increased risk for several tobacco related cancers . ^^^ To examine the potential role of GSTM polymorphisms in risk for oral cancer in African Americans and Caucasians , the prevalences of the GSTM 1 null and GSTM 3 intron 6 polymorphisms were examined in 63 African American and 101 Caucasian patients with histologically confirmed primary oral cancer , as well as in 133 African American and 213 Caucasian matched control subjects . ^^^ In African Americans , the odds ratio for oral cancer associated with the GSTM 1 ( 0 / 0 ) genotype was 3 . 1 [ 95 % confidence interval ( CI ) = 1 . 1 8 . 5 ] , with the association between the GSTM 1 ( 0 / 0 ) genotype and oral cancer risk strongest in heavy smokers [ i . e . > 24 pack years ; odds ratio ( OR ) = 5 . 4 , 95 % CI = 1 . 2 24 ] . ^^^ These results suggest that the GSTM 1 null and GSTM 3 intron 6 polymorphisms play an important role in risk for oral cancer among African Americans and implicates the mu class of GSTs as important tobacco carcinogen detoxifying enzymes in this population . . ^^^ |
