J Pediatr Hematol Oncol. 2023 Jan 1;45(1):41-43. doi: 10.1097/MPH.0000000000002544. Epub 2022 Sep 12.

Abstract

Hereditary hemolytic anemias are a heterogenous group of disorders that include membranopathies, enzymopathies, and hemoglobinopathies. Genetic testing is helpful in the diagnostic workup when the clinical and laboratory workup is not conclusive. Here, we present a case of a 21-month-old female who was initially diagnosed with hereditary spherocytosis based on the presence of a variant of unknown significance in the SPTB gene. Further genetic workup revealed a homozygous glucose 6 phosphate isomerase mutation and the patient was ultimately diagnosed with glucose 6 phosphate isomerase deficiency.
