Three abnormal hemoglobins identified as G by their electrophoretic mobility and performance on resin chromatography have been discovered in three healthy unrelated Negro individuals in Texas. These three G hemoglobins have been shown to belong to the same molecular species and to have a substitution in the 43rd residue of the β chain.
