Hereditary spherocytosis (HS) is the most common hereditary hemolytic disease with defects in red blood cells (RBC) membrane proteins caused by mutations in membrane protein genes, like SPTB, SPTA1 and ANK1. Gilbert syndrome (GS) is a disease characterized by a mild deficiency of uridine diphosphate-glucuronosyltransferase 1A1 (UGT1A1) enzyme activity and unconjugated hyperbilirubinemia, largely caused by UGT1A1 mutations. The two inherited diseases HS and GS are rarely occurred in the same patient and are easy to be misdiagnosed, resulting in excessive diagnosis and treatment. Here, we report a rare case of HS combined with GS due to mutations in the SPTB and UGT1A1 genes. A 50-year-old man who had an over 40-year history of jaundice was admitted to our hospital owing to fatigue and fever. His blood analysis showed low hemoglobin (74 g/L), high reticulocyte (23.5%) and high serum bilirubin (65 μmol/L); abdominal ultrasound revealed calculous cholecystitis and splenomegaly. Considering a possible diagnosis of hemolytic anemia, further examinations showed 42% spherocytes in blood smears and high erythroid lineage hyperplasia in bone marrow. Subsequently, 151 jaundice-related genes panel sequencing was done and results showed SPTB p.N1260fs and UGT1A1 p.G71R mutations. Then the patient was diagnosed with HS complicated with GS. Anti-infection and supportive treatments were providing to the patient, while infection removed, the hemoglobin recovered to normal, and no additional t...
