Also known as:

Comments: Associated with HbF levels is a subset of Cooperative Study of Sickle Cell Disease (CSSCD) participants. Associated with HbF level in Saudi W (benin haplotype) patients, but was not replicated in Saudi E (AI haplotype), Indian (AI haplotype) and a different subset of African-American (CSSD) patients with sickle cell anaemia (SCA, βS homozygotes). Associated with the hydroxyurea-induced increment in children with sickle cell disease (SCD), but not baseline or maximum HbF levels. The association was not replicated in a pediatric cohort of SCA from Brazil. Associated with HbF in Chinese Zhuang β-thalassemia intermedia patients.
