Abstract excerpt
Hereditary persistence of fetal hemoglobin (HPFH) can be generally classified into deletional and nondeletional forms. The family described in the present study has characteristics of both types of HPFH. The proband is a healthy 30-year-old black woman. Analysis of her hemoglobin revealed 40.4% HbS, 40.9% HbF (G gamma/A gamma ratio 0.53), 16.8% HbA, and 1.9% HbA2. All of her hematologic indices were normal, and...
