Hb F-Meinohama or alpha 2 gamma 2 (5 Glu replaced by Gly; 75 Ile; 136 Gly).

During a survey of blood samples from newborn babies, a new fetal hemoglobin variant was observed which had a substitution of the normally occurring glutaminyl residue at position gamma 5 (A2) for a glycyl residue. The abnormal gamma chain had an isoleucyl residue at position 75 and a glycyl residue at position 136.
