Abstract
DURING the first 10 weeks of human embryonic life, there exist unique haemoglobins designated Gower 1 and Gower 2, and it has been suggested that Hb Gower 1 is a tetramer consisting of ɛ chains (ɛ4) (ref. 1). Haemoglobin Portland has also been described in infants with developmental abnormalities2 and neonates with severe α–thalassaemia, the Bart's hydrops foetalis syndrome3,4. Hb Portland is composed of two γ chains and two ζ chains5.
