  • Title: Hemoglobin Willamette (alpha2beta2 51Pro replaced by Apg (D2)) a new abnormal human hemoglobin.
    Author: Jones RT, Koler RD, Duerst ML, Dhindsa DS.
    Journal: Hemoglobin; ; 1(1):45-57. PubMed ID: 1052170.
    Abstract:
    A hemoglobin variant with the same electrophoretic mobility as hemoglobin S was found in three generations of a black family. No clinical symptoms or findings were present in subjects heterozygous for this mutant. Except for target forms of mature erythrocytes, they have no abnormal hematologic findings. Structural studies demonstrated a previously undescribed substitution, beta51 Pro replaced by Arg, in the abnormal fraction which accounts for about one-third of the total hemoglobin. This fraction is more unstable in vitro at 65 degrees than normal A hemoglobin. Both whole blood and purified abnormal hemoglobin have increased oxygen affinity and a slightly decreased Bohr effect.
