[A case of Gilbert syndrome caused by UGT1A1 gene compound heterozygous mutations].

A case of Gilbert syndrome (GS) with a heterozygous mutation in the UGT1A1 gene is reported. The patient had no symptoms except for recurrent sclera icterus since childhood. Laboratory examinations revealed an elevated unconjugated bilirubin. Biliary obstruction, hemolysis and other diseases that might cause jaundice were excluded. UGT1A1*28 and c.211G>A heterozygous mutations in UGT1A1 gene were found, which may be another type of mutation causing GS in Chinese population.
