Contribution of G71R mutation to Gilbert's syndrome phenotype in a Greek patient: A case report.

Gilbert's syndrome is characterized by a benign indirect hyperbilirubinemia. It has often been underestimated and undiagnosed because of its mild symptoms; although it is not as rare as was once believed when its frequency was estimated using data originating from biochemical tests. Based on molecular techniques, the occurrence of Gilbert's syndrome has changed, increasing to 10% in the Caucasian population.
