Abstract
The G.gamma. and A.gamma. genes of an individual homozygous for the British form of A.gamma. nondeletion hereditary persistence of fetal hemoglobin have been cloned and partially sequenced. The G.gamma. gene was normal, but the A.gamma. gene was found to have a single base change (T .fwdarw. C) at - 198 bp relative to the cap site. Supercoiled plasmids containing normal .gamma.-genes or the mutant A.gamma.-gene displayed an S1-hypersensitive site immediately 5'' to the base change.
