Core Tip

Core Tip: Hereditary spherocytosis (HS) is a common type of hemolytic anemia caused by red cell membrane disorder. HS type 1 (HS1) typically results from mutations in ankyrin (ANK1). Newborns with HS1 usually only exhibit anemia and mild jaundice. This paper reports on a Chinese neonate who developed severe, intractable neonatal jaundice unrelated to immune-mediated hemolysis. The patient underwent two exchange transfusions and one plasmapheresis, which significantly reduced his extreme hyperbilirubinemia. Using trio clinical exome sequencing, we identified a de novo null heterozygous mutation in the patient's ANK1 gene: c.841C > T(p.Arg281Ter), which resulted in the premature termination of ANK1 protein.
