Utilization of different methodologies for the characterization of Hb Hasharon heterozygotes.

Hb Hasharon has an electrophoretic mobility similar to that of Hb S in cellulose acetate and a mobility between Hb S and C at acid pH. In high-performance liquid chromatography, Hb Hasharon shows a distinct chromatographic profile and retention time. The origin of this variant is a mutation in codon 47 (GAC --> CAC) of the alpha2-globin gene, resulting in the replacement of asparagine by histidine during the translation process.
