Hemoglobin Sunshine Seth - alpha 2 (94 (G1) Asp replaced by His) beta 2

Hemoglobin Sunshine Seth in which a histidyl is substituted for an aspartyl residue at position 94 of the alpha chain was detected at birth in a Caucasian male infant during cord blood screening and is present also in the mother and a male sibling. Although the substitution is in the alpha 1 beta 2 contact, it is without obvious deleterious effect on the hematological parameters or the health of the affected individuals.
