An abnormal fetal hemoglobin, designated hemoglobin FTexas, was found in the cord blood of five Negro infants (all related and three of them siblings) and of one Caucasian infant. Studies on the chemical structure of this variant indicate that there is a substitution of a lysyl residue for either the fifth or sixth glutamyl residue of the gamma-chain.
