Occasionally jaundice (a slight yellowish color of the skin or whites of the eyes) may occur.. Gilbert syndrome is due to a genetic variant in the UGT1A1 gene which results in decreased activity of the bilirubin uridine About Community. UNLABELLED: Gilbert syndrome is a common autosomal dominant hereditary condition with incomplete penetrance and characterized by intermittent unconjugated hyperbilirubinemia in the absence of hepatocellular disease or hemolysis. Uridine 5'-diphospho-glucuronosyltransferase (UDP-glucuronosyltransferase, UGT) is a microsomal glycosyltransferase (EC 2.4.1.17) that catalyzes the transfer of the glucuronic acid component of UDP-glucuronic acid to a small hydrophobic molecule. Black and Billing (1969) found hepatic bilirubin UDP-transferase to be about 25% of normal in 11 patients with Gilbert syndrome. The reduced activity of UGT1A1 (UDP-Glucuronyl transferase1A1 enzyme) causes non-conjugated hyperbilirubinemia, and consequently leads to Gilbert's and Crigler-Najjar syndromes ( Maruo et al., 2016; Sugatani et al., 2008 ). 10 Of the many causes of jaundice, Gilbert s syndrome (GS) is probably the most common and most innocu- 12 Black M, Billing BH.

Diagnosis Schmid (1995) pointed out that Gilbert syndrome is an entirely benign and clinically inconsequential entity, requiring neither treatment nor long-term medical attention. The hatched area indicates the normal range (mean 2 SD. Since there is low glucuronyl transferase activity in the liver there is a risk for anesthetic toxicity with a possibility of a catastrophic outcome. The decreased activity of UDP-glucuronyl transferase makes these patients vulnerable to usual doses of anaesthetic drugs. Avoiding prolonged fasting, maintainence of adequate hydration, use of short acting drugs which undergo least hepatic uptake
