Abstract:
We have identified a new α chain hemoglobin (Hb) variant in a Chinese family. Sequencing of the amplified α2-globin gene revealed a 9 nucleotide (nt) deletion (-C GAG TAT GG) at codons 22-25, which results in a predicted α-globin chain that is missing amino acid residues 23-25 (Glu-Tyr-Gly) and the formation of Hb Zhanjiang.
