Abstract
During the course of a survey, a new hemoglobin, designated hemoglobin Yoshizuka, has been encountered in a Japanese family. Clinically, mild anemia was noted in five of six heterozygous individuals but no other significant abnormalities were found. Hemoglobin Yoshizuka is characterized by the substitution of aspartic acid for asparagine at the tenth residue of the G helix in the β-chain. Reduced oxygen affinity with almost normal heme-heme interaction was found to be a property of this abnormal hemoglobin.
