Novel α-spectrin mutation in trans with α-spectrin causing severe neonatal jaundice from hereditary spherocytosis.
Novel α-spectrin mutation in trans with α-spectrin causing severe neonatal jaundice from hereditary spherocytosis.
We evaluated a neonate with severe jaundice but a negative family history. Spherocytes were present and suspected hereditary spherocytosis was confirmed by osmotic fragility and eosin-5-maleimide erythrocyte staining. We found he was a compound heterozygote for two pathogenic mutations in the gene encoding α-spectrin: a previously reported α(LEPRA) inherited from his asymptomatic mother, and a novel α-spectrin mutation in intron 45 +1 disrupting the consensus splice site, from his asymptomatic father.
