Fetal hemoglobin in sickle cell disease patients from Tanzania

Levels of fetal hemoglobin have been associated with differences in severity and outcome of sickle cell disease (SCD). While some genetic associations have been reported between SNPs and HbF level, little of the variance in the trait is explained, and most studies have focused on African American, rather than African samples. We have carried out a GWAS in a collection of SCD patients from Dar es Salaam, Tanzania. This sample represents a diverse, metropolitan collection of individuals from East Africa. Omni 2.5M genotypes and HbF levels (measured after 5 years of age) are available.
