A Rare Hemoglobin Variant Which Interfered Hemoglobin A1C Result: Hemoglobin South Florida (β1(NA1)Val>Met, GTG>ATG; HBB: c.4G>A)

Hb South Florida is a rare hemoglobin beta chain variant that is not associated with any clinical disorder. We report a heterozygous Hb South Florida (β1(NA1)Val>Met, GTG>ATG; HBB:c.4G>A) case determined during a premarital screening program. This hemoglobin variant can be identified with high performance liquid chromatography analysis confirmed with DNA sequencing. We emphasize in our study the importance of an interdisciplinary collaborative study at the provincial basis for the success of the hemoglobinopathy control program.
