摘要: We used resequencing and genotyping in African Americans with sickle cell anemia (SCA) to characterize associations fetal hemoglobin (HbF) levels at the BCL11A, HBS1L-MYB β-globin loci. Fine-mapping of HbF association signals these loci confirmed seven SNPs independent effects increased explained heritable variation from 38.6% 49.5%. also identified rare missense variants that causally implicate MYB production.
