UGT1A1 gene.c.A(TA)7TAA(*28)
Active
Description
The presence of an additional TA repeat in the TATA region of the UGT1A1 promoter (ie, 7 TA repeats; UGT1A1*28, rs8175347) markedly reduces the level of hepatic bilirubin UDP-glucuronosyltransferase 1A1 (UGT1A1), the enzyme necessary for the conjugation of bilirubin. Individuals homozygous for the UGT1A1*28 allele develop Gilbert syndrome, a condition characterized by periods of mild unconjugated hyperbilirubinemia. In addition, individuals positive for the UGT1A1*28 allele are more likely to experience severe adverse effects during irinotecan chemotherapy. Identifying a patient's genotype for the UGT1A1 allele helps determine appropriate starting dosages for irinotecan, reducing the risk of severe toxicity and improving overall therapy.
