Purpose : The incidence of neonatal hyperbilirubinemia is twice as high in East Asians as in Caucasians. However, its metabolic basis has not been clearly explained. The UDP-glucuronosyltransferase gene(UGT1A1) mutation was found to be a risk factor of neonatal hyperbilirubinemia. We studied whether neonatal hyperbilirubinemia is associated with the 1828G>A(rs 10929303) polymorphism of the UGT1A1 gene, which encodes for a...
The Association of Neonatal Hyperbilirubinemia with UGT1A1 and CYP1A2 Gene Polymorphism in Korean Neonates
Hoon Kang, Jun Ho Lim, Ji Sook Kim, Eun Ryoung Kim, Sung Do Kim, Hee Jae Lee, Joo Ho Chung
Clin Exp Pediatr. 2005;48(4):380-386.   Published online April 15, 2005
Purpose : The incidence of nonphysiologic neonatal hyperbilirubinemia is twice as high in East Asians as in whites. Recently, UGT1A1 mutation was found to be a risk factor for neonatal hyperbilirubinemia. In congenitally-jaundiced Gunn rats, which lack expression of UDP-glucuronosyltransferase, alternative pathways can be stimulated by inducers of CYP1A1 and CYP1A2 enzymes. CYP1A2 plays a major role in bilirubin degradation...
