Analysis of bilirubin UDP-glucuronosyltransferase gene mutations in an unusual Crigler-Najjar syndrome patient.
Crigler-Najjar (CN) syndrome is a rare autosomal recessive inherited disorder characterized by non-hemolytic, unconjugated hyperbilirubinemia. The levels of serum bilirubin and the response to phenobarbital treatment have been used to classify CN syndrome into two types: CN I and II. Mutations of the UGT1A1 gene have been found to be responsible f...
متن کاملCrigler-Najjar syndrome type II in a Chinese boy resulting from three mutations in the bilirubin uridine 5′-diphosphate-glucuronosyltransferase (UGT1A1) gene and a family genetic analysis
BACKGROUND The UGT1A1 gene encodes a responsible enzyme, UDP-glucuronosyltransferase1A1 (UGT1A1), for bilirubin metabolism. Many mutations have already been identified in patients with inherited disorders with unconjugated hyperbilirubinemia, such as Crigler-Najjar syndromes and Gilbert's syndrome. CASE PRESENTATION In this report, we presented a boy with intermittent unconjugated hyperbiliru...
متن کاملHematologically important mutations: bilirubin UDP-glucuronosyltransferase gene mutations in Gilbert and Crigler-Najjar syndromes.
Gilbert and Crigler-Najjar syndromes are familial unconjugated hyperbilirubinemias caused by genetic lesions involving a single complex locus encoding for bilirubin UDP-glucuronosyltransferase (UGT1A1) gene. Over the last years a number of different mutations affecting this gene have been characterized. In this report is provided a summary of reported Gilbert and Crigler-Najjar syndromes associ...
متن کاملHereditary Spherocytosis Coexisting with UDP-Glucuronosyltransferase Deficiency Highly Suggestive of Crigler-Najjar Syndrome Type II
Patients with co-existing hereditary spherocytosis (HS) and UDP-glucuronosyltransferase 1A1 (UGT1A1) deficiency as Gilbert's syndrome (GS) have been reported, and previous studies have demonstrated an increased risk for developing gallstones in patients with co-inheritance of GS and HS. We experienced an interesting case of HS showing persistent jaundice after splenectomy, and upon further eval...
متن کاملMolecular Analysis of the UGT1A1 Gene in Korean Patients with Crigler-Najjar Syndrome Type II
PURPOSE Crigler-Najjar syndrome type II (CN-2) is characterized by moderate non-hemolytic unconjugated hyperbilirubinemia as a result of severe deficiency of bilirubin uridine diphosphate-glucuronosyltransferase (UGT1A1). The study investigated the mutation spectrum of UGT1A1 gene in Korean children with CN-2. METHODS Five Korean CN-2 patients from five unrelated families and 50 healthy contr...
