Also known as:
Comments: The structural hemoglobin variant of Gγ with two amino acid replacements in cis found in the umbilical cord blood of a neonate in Madrid. The neonate born after a normal 40-week gestation and the main abnormal feature was a decreased MCV of 76 fl, at 1.5 years old. The neonate also carried the –α3.7 deletion.
