Hb Hekinan in a Taiwanese subject: a G-->T substitution at codon 27 of the alpha1-globin gene abolishes an HaeIII site

Hemoglobin. 2007;31(4):495-8. doi: 10.1080/03630260701590368.

Abstract

We recently observed a heterozygote for Hb Hekinan in a Taiwanese subject. The molecular lesion of Hb Hekinan is a substitution of G-->T at codon 27 of the alpha1-globin gene, which abolishes an HaeIII restriction enzyme site. Hb Hekinan [alpha27(B8)Glu-->Asp, GAG-->GAC (alpha2)] has not been found in Taiwan. This variant can be detected by high performance liquid chromatography (HPLC) but not by capillary or cellulose electrophoresis.
