Preferred Label : Gilbert syndrome;
CISMeF acronym : HBLRG;
Type : Phenotype, molecular basis known;
Alternative titles and symbols : Hyperbilirubinemia I; Hyperbilirubinemia, arias type; Hyperbilirubinemia, gilbert type; HBLRG;
Description : The hereditary hyperbilirubinemias (Wolkoff et al., 1983) include (1) those resulting
in predominantly unconjugated hyperbilirubinemia: Gilbert or Arias syndrome, Crigler-Najjar
syndrome type I (218800), and Crigler-Najjar syndrome type II (606785); and (2) those
resulting in predominantly conjugated hyperbilirubinemia: Dubin-Johnson syndrome (237500),
Rotor syndrome (237450), and several forms of intrahepatic cholestasis (147480, 211600,
214950, 243300). Detailed studies show that patients with Gilbert syndrome have reduced
activity of bilirubin glucuronosyltransferase (Bosma et al., 1995, Koiwai et al.,
1995). - Genetic Heterogeneity of Hyperbilirubinemia See also Crigler-Najjar syndrome
type I (HBLRCN1; 218800), Crigler-Najjar syndrome type II (HBLRCN2; 606785), and transient
familial neonatal hyperbilirubinemia (HBLRTFN; 237900), all caused by mutation in
the UGT1A1 gene (191740) on chromosome 2q37; Dubin-Johnson syndrome (DJS, HBLRDJ;
237500), caused by mutation in the ABCC2 gene (601107) on chromosome 10q24; and Rotor
syndrome (HBLRR; 237450), caused by digenic mutation in the SLCO1B1 (604843) and SLCOB3
(605495) genes, both on chromosome 12p.;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutations in the uridine diphosphate glycosyltransferase 1 gene (UGT1A1,
191740.0010);
Laboratory abnormalities : Decreased hepatic UDP-glucuronyl-transferase activity; Hyperbilirubinemia, non-hemolytic unconjugated (may rise with fasting or dehydration); Normal liver function test;
