Interaction with the alpha-thalassaemia phenotypes lowers the proportion of Hb S in the sickle cell trait and influences the mean cell volume and proportional Hb A2 in homozygous sickle cell (SS) disease. By assigning somewhat arbitrary values to the alpha-thalassaemia 1 and alpha-thalassaemia 2 phenotypes in these conditions, it has been possible to investigate the patterns of inheritance of alpha-thalassaemia in black populations. The results strongly support the hypothesis that the alpha-thalassaemia 1 phenotype represents homozygosity for alpha-thalassaemia 2.
与α地中海贫血表型相互作用会降低镰状细胞性状中Hb S的比例,并影响纯合镰状细胞(SS)病的平均细胞体积和Hb A2比例。通过在这些情况下对α地中海贫血1和α地中海贫血2表型赋予一些任意值,得以研究黑人人群中α地中海贫血的遗传模式。结果有力地支持了α地中海贫血1表型代表α地中海贫血2纯合子的假说。
