Patent ID: 7083923

Claim:
A method of detecting the presence of glutathione S-transferase alleles comprising the steps of: obtaining a sample of genomic DNA; amplifying a first portion of the sample with primers for GSTM1 and CDK2; amplifying a second portion of the sample with primers for GSTT1 and GSTM3; amplifying a third portion of the sample with primers for GSTP 1; and detecting the alleles and their gene dosage; wherein said detecting shows the presence or absence of the alleles of GSTM1, GSTM3, GSTT1, and GSTP1, wherein said GSTM1 alleles are GSTM1*null, GSTM1*A, and GSTM1*B, wherein said GSTM3 alleles are GSTM3*A and GSTM3*B, wherein said GSTT1 alleles are GSTT1*null and GSTT1*T1, and said GSTP1 alleles are GSTP1*A GSTP 1*B, GSTP1*C and GSTP1*D, and wherein said detecting shows the gene dosages of GSTM1 and GSTT1 alleles.
