Independently of its African roots, the HbS gene is also indigenous to the Middle East and India where it can be on an Arab-Indian (AI) HBB haplotype. This haplotype is associated with high levels of fetal hemoglobin (HbF) and increased HbF improves many complications of sickle cell disease. 1 Polymorphisms in BCL11A (chr 2p) and HBS1L-MYB (chr 6q) and in elements linked to HBB (chr 11p) are associated with HbF level. In AI haplotype HbS homozygotes, SNPs in BCL11A and HBS1L-MYB accounted for 8.8% of HbF variance.
