A heterozygous G > A transition at the 5' splicing donor consensus sequence in intron 14 leading to exon 14 skipping (IVS14+1 G > A, DPYD*2A) with partial loss of enzyme activity may be partly responsible for 5FU induced toxicity, whereas irinotecan associated toxicity may in part be explained by an aberrant UGT1A1 promoter (TA)(n) genotype underlying Gilbert's syndrome with reduced liver glucuronidation activity.

The most common genotype of Gilbert syndrome is the homozygous polymorphism A(TA)7TAA in the promoter of the gene for UDP-glucuronosyltransferase 1A1 (UGT1A1), which is a TA insertion into the promoter designated UGT1A1*28.

Because the most common clinical condition associated with jaundice in adults is Gilbert's syndrome, which is characterized by an allelic polymorphism in the UGT1A1 promoter, hyperbilirubinemia was monitored in humanized UGT1 mice that expressed either the Gilbert's UGT1A1*28 allele [Tg(UGT1(A1*28))Ugt1(-/-) mice] or the normal UGT1A1*1 allele [Tg(UGT1(A1*1))Ugt1(-/-) mice].

This and other findings suggest the existence of a mild and a more severe form of Gilbert's syndrome, depending on whether the gene defect lies in the promoter sequence upstream of UGT1*I exon I, as here (mild), or in the coding sequence (severe) of the gene.
