Finally, a dominant-like β-thalassemia, Hb Houston (codon 127 A>G), was also reported for the first time in Iraq (a missense mutation at codon 127 in exon III that produces an unstable hemoglobin and thalassemia intermedia phenotype in the heterozygous state) [33]. The gene discussed is GSTM1; the disease is beta-thalassemia intermedia.
