Gilbert syndrome, a chronic nonhemolytic unconjugated hyperbilirubinemia, is associated with thymine-adenine (TA) insertions in the UGT1A1 (UDP glucuronosyltransferase 1 family, polypeptide A1) promoter. The UGT1A1 promoter genotype also correlates with toxicity induced by the chemotherapeutic drug irinotecan. Current closed-tube assays for genotyping the UGT1A1 (TA)(n) promoter polymorphism require multiple labeled probes and/or have difficulty classifying the (TA)(5) and (TA)(8) alleles.
