NCIt definition : Human UGT1A1 wild-type allele is located in the vicinity of 2q37 and is approximately
13 kb in length. This allele, which encodes UDP-glucuronosyltransferase 1-1 protein,
plays a role in the transformation of small lipophilic molecules into water-soluble
metabolites. Certain allelic variants of the UGT1A1 gene cause Crigler-Najjar syndrome
type I, type II, Gilbert syndrome or transient familial neonatal hyperbilirubinemia.;
