Association of SNP in exon 1 of HBS1L with hemoglobin F level in beta0-thalassemia/hemoglobin E.
Increase in fetal hemoglobin (Hb F) reduces globin chain imbalance in beta-thalassemia, consequently improving symptoms. QTL mapping together with previous genome-wide association study involving approximately 110,000 gene-based SNPs in mild and severe beta(0)-thalassemia/Hb E patients revealed SNPs in HBS1L significantly associated with severity and Hb F levels. Given its potential as binding site for transcription factor activator protein 4, HBS1L exon 1 C32T polymorphism was genotyped in 455 cases, providing for the first time evidence that C allele is associated with elevated Hb F level among beta(0)-thalassemia/Hb E patients with XmnI-(G)gamma-/-and XmnI-(G)gamma+/-polymorphisms.
