UDP-Glucuronosyltransferase 1A1 gene polymorphisms and total bilirubin levels in an ethnically diverse cohort of women.
The objective of this study was to investigate variations in UGT1A1 polymorphisms and haplotypes among African-American and Caucasian women and to assess whether variants other than UGT1A1*28 are associated with total serum bilirubin levels. The (TA)(n) repeats and 14 single nucleotide polymorphisms (SNPs) in the UGT1A1 gene were genotyped in 335 African Americans and 181 Caucasians. Total seru...
متن کاملPolymorphisms and haplotypes of the UDP-glucuronosyltransferase 2B7 gene promoter.
Identification of functional polymorphisms in the UDP-glucuronosyltransferase 2B7 (UGT2B7) gene predicting interpatient variability in the glucuronidation of drugs that are primarily metabolized by UGT2B7 has been the subject of many studies. These studies have shown linkage disequilibrium (LD) covering the region from -2 kb to 16 kb of the UGT2B7 gene. We identified three novel single-nucleoti...
متن کاملGenotype frequencies of UDP-glucuronosyltransferase 1A1 promoter gene polymorphism in the population of healthy Croatian pre-scholars.
Increased serum bilirubin levels in patients with Gilbert syndrome (GS) are caused by reduction of hepatic activity of bilirubin glucuronosyltranferase to about 30% of normal. UGT1A1 genetic polymorphism with absent or very low bilirubin UDP-glucuronosyltransferase (B-UGT) activity is associated with Gilbert's syndrome (GS) and other hyperbilirubinemias. The genetic basis of GS is the insertion...
متن کاملRacial variability in the UDP-glucuronosyltransferase 1 (UGT1A1) promoter: a balanced polymorphism for regulation of bilirubin metabolism?
A polymorphism in the promoter of the UDP-glucuronosyltransferase 1 (UGT1A1) gene has been shown to cause Gilbert syndrome, a benign form of unconjugated bilirubinemia. Promoters containing seven thymine adenine (ta) repeats have been found to be less active than the wild-type six repeats, and the serum bilirubin levels of persons homozygous or even heterozygous for seven repeats have been foun...
متن کاملIs Ceftriaxone-Induced Biliary Pseudolithiasis Influenced by UDP-Glucuronosyltransferase 1A1 Gene Polymorphisms?
Ceftriaxone (cfx), a third-generation cephalosporin antibiotic, leads to transient cholelithiasis in some children, also known as pseudolithiasis. However, the underlying pathogenetic mechanism of this adverse effect has not yet been elucidated. We describe 3 children with ceftriaxone-induced pseudolithiasis, who were also carriers of the A(TA)(7)TAA polymorphism of the UGT1A1 gene, implying th...
