Haemoglobin F Texas II (α₂γ₂⁶ Glu→Lys), the Second of the Haemoglobin F Texas Variants

Abstract

S ummary A survey of 13 ,000 cord bloods in Great Britain yielded an electrophoretically abnormal variant of Haemoglobin F which resembled Haemoglobin F Texas. Haemoglobin F Texas might be either α 2 γ 2 5G1u→Lys or α 2 γ 2 6Glu→Lys . The first has been described and was named Haemoglobin F Texas I. The present variant has the same substitution in the sixth residue of the γ chain and is designated as Haenioglobin F Texas II.
