493名汉族新生儿胎儿血红蛋白中Gγ/Aγ值分布为:高Gγ(81～89％)3.9％、低Gγ(34～45％)2.6％,其余正常。8例高Gγ的基因型为-Gγ-AGγ-Aγ-/-Gγ-Aγ;10例低Gγ者均为γ基因缺失型,其中7例基因型为-GAγ-/-Gγ-Aγ-。
The distribution of Gγ / Aγ in fetal hemoglobin of 493 newborn infants was 3.9% for high Gγ (81-89%) and 2.6% for low Gγ (34-45%), the others were normal. The genotypes of 8 cases with high Gγ were -Gγ-AGγ-Aγ - / - Gγ-Aγ, and the other 10 cases with low Gγ were all deleted. The genotype of 7 cases was -GAγ - / - Gγ-Aγ-.
