摘要
GSTT1 and GSTM1 genes possess an inherited deletion associated with a lack of enzyme activity. The heterozygous condition of this deletion is difficult to determine in low-quality DNA with existing PCR protocols. We designed and validated a multiplex real-time PCR assay by adapting the Delta Delta Ct relative quantification method for the analysis of GSTY1 and GSTM1 markers to accurately differentiate the three genotypes (*1/1, *1/0, and *0/0) in degraded DNA from formalin-fixed paraffin-embedded tissue. Gene copy number values obtained provide for unambiguous homozygous and heterozygous differentiation. The efficacy shown by the PCR assay endorses its usefulness for complete genotyping of glutathione S-transferases in archival tissues. (C) 2008 Elsevier Inc. All rights reserved.
