Induced heteroduplex genotyping of TNF-alpha, IL-1beta, IL-6 and IL-10 polymorphisms associated with transcriptional regulation.

We describe the construction and use of 7 induced heteroduplex generators, reagents for the rapid and unequivocal genotyping of nucleotide sequence polymorphism in TNF-alpha, IL-1beta, IL-6 and IL-10. Polymorphisms detected are those previously associated with regulation of gene transcription: TNF-alpha positions -308 and -238; IL-1beta position +3953; IL-6 position -174; and IL-10 positions -1082, -819 and -592. The reagents were used for analysis of allele and haplotype frequencies in a population of healthy Caucasian volunteer blood donors. Copyright 1999 Academic Press.
