Here we use a new mouse model that targets deletion of the Ugt1 locus and the Ugt1a1 gene in liver to promote hyperbilirubinemia-induced seizures and central nervous system toxicity.
The UDP-glucuronosyltransferase 1A1 (UGT1A1) polymorphism UGT1A1*28 (*28)/*28 has been linked to an increased risk of hyperbilirubinemia in patients with CML who receive nilotinib.
Although Gilbert's syndrome is usually quite benign UGT1A1(TA)n genotyping is important in exclusion of more serious causes of hyperbilirubinemia and since it has significant implications for personalised medicine.
Tocilizumab-induced hyperbilirubinemia in Japanese patients with rheumatoid arthritis: its association with UDP glucuronosyltransferase 1A1 gene polymorphisms.
Variation of a short (TA)(n) repeat sequence (rs8175347) covering the TATA box of UGT1A1 (UDP-glucuronosyltransferase1A1) is associated with hyperbilirubinaemia (Gilbert's syndrome) and adverse drug reactions, and is used for dosage advice for irinotecan.
A prospective study was conducted to investigate the effects of birth body weight, sex, mode of delivery, glucose-6-phosphate dehydrogenase (G6PD) deficiency, variant UDP-glucuronosyltransferase 1A1 (UGT1A1) gene, and hepatic solute carrier organic anion transporter 1B1 (SLCO1B1) gene on hyperbilirubinemia in neonates who were breast-fed.
Adult Tg(UGT1(A1*28))Ugt1(-/-) mice expressed elevated levels of total bilirubin (TB) compared with Tg(UGT1(A1*1))Ugt1(-/-) mice, confirming that the promoter polymorphism associated with the UGT1A1*28 allele contributes to hyperbilirubinemia in mice.
UDP-glucuronosyltransferase 1A1 polymorphism, UGT1A1*28, which is associated with atazanavir-induced hyperbilirubinemia, is less common in Asians than in Caucasians.
Genetic factors influencing severe atazanavir-associated hyperbilirubinemia in a population with low UDP-glucuronosyltransferase 1A1*28 allele frequency.
(TA)7 promoter polymorphism in the gene encoding the bilirubin conjugating enzyme UDP-glucuronosyltransferase 1A1 (UGT1A1) potentiates hyperbilirubinemia in G-6-PD deficient neonates.
Relationship between hyperbilirubinaemia and UDP-glucuronosyltransferase 1A1 (UGT1A1) polymorphism in adult HIV-infected Thai patients treated with indinavir.
A case-control study was designed to investigate the effects of eight known risk factors [breast feeding, ABO incompatibility, premature birth, infection, cephalohematoma, asphyxia, glucose-6-phosphate dehydrogenase (G6PD) deficiency, and variant UDP-glucuronosyltransferase 1A1 (UGT1A1) gene] and a suspicious analog [organic anion transporter 2 (OATP 2) gene] on severe hyperbilirubinemia in Taiwanese neonates.
Elucidation of both the structure of the UGT1 gene complex, and the Mrp2 (cMoat) gene which encodes the canalicular conjugate export pump, has led to a greater understanding of the genetic basis of hyperbilirubinemia.
In summary, recombinant adenoviral vectors were used to demonstrate in vivo complementation of the genetic defect in Gunn rat livers with the HUG Br1 cDNA leading to a resolution of hyperbilirubinemia lasting approximately 7 weeks.
