Hereditary persistence of fetal hemoglobin (HPFH) is a benign condition in which significant fetal hemoglobin production continues well into adulthood, disregarding the normal shutoff point after which only adult-type hemoglobin should be produced. The percentage of incorrect expression might be as low as 10%-15% or as high as 100% of the total hemoglobin, usually higher in homozygotes than in heterozygotes. The present case is a typical example of homozygous HPFH.
胎儿血红蛋白遗传性持续存在(HPFH)是一种良性病症,其中胎儿血红蛋白的大量产生会持续到成年期,无视正常的关闭点,正常情况下超过该点后仅应产生成人型血红蛋白。错误表达的百分比可能低至总血红蛋白的10%-15%,也可能高达100%,通常纯合子中的比例高于杂合子。本病例是纯合子HPFH的典型例子。
