title: A new unstable and low oxygen affinity hemoglobin variant: Hb J-Auckland [beta 25(B7)Gly----Asp].
abstract: Hb J-Auckland is a new hemoglobin variant with the amino acid substitution beta 25(B7)Gly----Asp. It is mildly unstable and has a low oxygen affinity. The propositus and a son, both heterozygous for Hb J-Auckland, have marginally low Hb values but no apparent clinical symptoms.
