The most common forms of hereditary persistence of fetal hemoglobin (HPFH) involve large deletions that remove the adult delta and beta genes but leave the paired fetal genes (G gamma and A gamma) intact. The size of these deletions has previously eluded exact definition. Using pulsed-field gel electrophoresis and the enzyme SfiI, which cuts only rarely in genomic DNA, we have constructed a lar...

Such questions have remained unanswered due to the lack of data available on the positions to which job seekers apply. Drawing on t...
