Abstract
A 30-year-old male couple from Ardabil city, Iran, were admitted for premarital screening. An abnormal band in HbS/D regions with high levels of HbF and HbA 2 led us to suspect the possibility of a compound heterozygous state of β-thalassemia in our affected proband. Therefore, beta globin chain sequencing of proband discovered a heterozygote combination of the Hb G-Coushatta [b22 (B4) Glu>Ala, HBB: c.68A>C) with HBB: IVS-II-1 (G>A) mutation as a compound heterozygote.
