The sequence of the A gamma globin gene from the affected chromosome of an individual heterozygous for the G gamma beta+ type of hereditary persistence of fetal haemoglobin (G gamma beta+ HPFH) is reported. With two exceptions, it is identical to one of the two allelic A gamma globin genes already sequenced and there is therefore no change which could explain the absence of its expression in the face of the persistent G gamma globin expression which is a feature of this condition.
报道了一名胎儿血红蛋白遗传性持续存在(Gγβ⁺ HPFH)的Gγβ⁺型杂合个体受影响染色体上的Aγ珠蛋白基因序列。除了两个例外,它与已测序的两个等位基因Aγ珠蛋白基因之一相同,因此不存在能够解释在这种情况下持续表达的Gγ珠蛋白存在时该基因却不表达的变化。
