According to recent research from Hannover, Germany, "Gilbert's syndrome is characterized by a functional promoter single nucleotide polymorphism (SNP) of the UDP-glucuronosyltransferase (UGT) 1A1 gene and represents a pharmacogenetic risk factor for irinotecan toxicity, but study data remain controversial. The active CPT-11 metabolite 7-ethyl-10-hydroxycamptothecin is detoxified by several UGT1A proteins, which include UGT1A7 with a high specific activity that may contribute to the risk of irinotecan toxicity in Gilbert's syndrome patients."

"Genotyping of the UGT1A1*28, UGT1A7 N129K/R131K, and UGT1A7-57T/G variants was done in 105 irinotecan-treated patients with...
