Abstract

The diagnosis of hereditary spherocytosis (HS) in a newborn infant is generally made on the basis of a positive family history, spherocytes on blood film and Coombs-negative hemolytic jaundice of variable severity with an elevated mean corpuscular hemoglobin concentration (MCHC) and a low mean corpuscular volume (MCV). In general, sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) quantification of erythrocyte membrane proteins is not needed to make the clinical diagnosis of HS. However, we observed that a neonate with no family history of HS, but with abundant spherocytosis on repeated blood films, Coombs-negative hemolytic jaundice and normal MCHC and MCV measurements, where SDS-PAGE revealed alpha-spectrin deficiency, a rare autosomal-recessive variety of HS that generally has a severe clinical phenotype.
