Although patients’ phenotypes are very heterogeneous, in terms of severity and life span, patients homozygous for this mutation usually exhibit chronic hemolytic anemia, report frequent and severe painful crises, and present extensive organ damage. This study aimed to identify genetic modifiers of SCA phenotypes and severity in the HBB Cluster, HBS1L-MYB intergenic region, BCL11A, KLF1, FOX3, and ZBTB7A genes, and assess their influence and prevalence in an Angolan population.engSickle cell anemiaGenetic modifiersAngolaFCT_UIDB/05608/2020FCT_UIDP/05608/2020FCT/Aga Khan_project nº 330842553conference poster
