Objective To discuss the clinical features, pathogenesis and diagnostic experience of hereditary spherocytosis (HS) accompanied with glucose-6-phosphate dehydrgenase deficiency (G6PD) deficiency. Methods Clinical features and diagnose of a 5-year-old case with HS accompanied with G6PD deficiency were analyzed, and realated literatures reviewed. Results The case was a 5-year-old boy referred to a hospital because of pallor and jaundice. Laboratory test results were as follows: red blood cell count 2.65×1012/ L, hemoglobin 70.50 g/L, mean corpuscular volume 78.61 fl, and mean sphered corpuscular volume 66.26 fl, reticulocyte ratio 18%; G6PD activity was 1.38 NBT. The peripheral red blood cells were of different sizes and mature, and spherocytes were observed. SDS-polyacrylamide gel electrophoresis and western blot shows the band 3 was partially deletion. Molecular analysis revealed the band 3 deficiency was caused by two mutations: one was a missensemutation c.113A >?C, and the other was a intron mutation c.349+27C >?T. A diagnosis of HS accompanied  with G6PD deficiency was therefore arrived. Conclusions HS accompanied with G6PD deficiency is a relatively uncommon phenomenon and might lead to misdiagnosis. Blood smear staining, thalassemia screening, mean sphered corpuscular volume and other laboratory detections could improve the accuracy of diagnosis.
