Restriction Enzyme Recognition Sites in the β-Globin Gene Cluster. RSIDs of SNPs present in restriction endonuclease sites in the β-globin-like gene cluster. (+) denotes the presence of the corresponding enzyme site while (−) denotes the absence in the five-major sickle cell haplotype (Benin (BEN), Central African Republic (CAR), Senegal (SEN), Cameroon (CAM) and Arab–Indian (AI)
