Genotyping of UGT1A1 promoter polymorphisms. DNA samples from five separate HIV-infected patients were amplified by PCR using primers specific for the UGT1A1 promoter region and subjected to electrophoresis on a 12% acrylamide gel. The presence of the A(TA)6TAA allele results in a 71-bp PCR product, whereas the A(TA)7TAA allele yields a 73-bp fragment. Genotypes are assigned as follows: 6/6, homozygous for the wild-type A(TA)6TAA allele; 7/7, homozygous for the A(TA)7TAA Gilbert's allele; 6/7, heterozygous for the A(TA)6TAA and A(TA)7TAA alleles.
