血红蛋白E(HbE)是世界上最常见的慢速异常Hb之一 ,是 β链第 2 6位谷氨酸被赖氨酸替代(α2 β2 GAA—AAG)。 1 979年梁植汉等首次经Hb化学分析确证我国有HbE〔1〕。据我省调查研究表明 ,HbE病发生率为 0 .1 0 3% ,β地中海贫血 (地贫 )发生率为 1 .86%。虽然HbE杂合子可无临床
Hemoglobin E (HbE) is one of the slowest abnormalities in the world, Hb, with glutamic acid at position 26 of the beta chain replaced by lysine (α2β2 GAA-AAG). In 1979, Liang Zhihan et al. First confirmed HbE by Hb chemical analysis in our country [1]. According to our province investigation and study shows that the incidence of HbE disease was 0.13%, β thalassemia (thalassemia) incidence was 1.86%. Although HbE heterozygotes are clinically non-clinical
