Abstract
High oxygen affinity hemoglobins (Hbs), characterized by a decreased ability to release oxygen to the tissues and a left-shifted oxygen dissociation curve, are a rare cause of secondary erythrocytosis. Here, we report a base substitution in the β-globin gene at codon 89 (AGT>AGG) in a kindred with familial erythrocytosis resulting in Hb Vanderbilt, a high oxygen affinity variant.
