Performing trait-association for SNPs across the HBS1L-MYB intergenic region on chromosome 6q24.3 in SCD patients from Tanzania, we detected significant association with HbF levels at HMIP-2, a globally-prevalent HbF QTL [7-9,11,15,17,19,31-35] residing within the MYB enhancer region [13]. The gene discussed is MYB; the disease is Schnyder corneal dystrophy.
