G gamma and A gamma globin genes are identical from -471 of the promoter midway through gamma IVSII in a Benin beta s haplotype associated with elevated fetal hemoglobin.

Abstract excerpt

In seven kindreds in which sickle cell (SS) patients had elevated (greater than 12%) fetal hemoglobin (Hb F), Milner and colleagues reported that a determinant for elevated Hb F and elevated F cells was linked to the beta s gene. Independently, the Senegal (SEN) beta s haplotype has been found in association with elevated Hb F in SS and beta-thalassemia patients. We have used the kindreds of Milner and colleagues...
