在贵州省三都水族自治县一水族家系中发现一种慢速血红蛋白,其电泳行为与Hb G相似,先证者及其他携带者均为杂合子,无临床症状及血液学异常。化学结构分析确定这种异常血红蛋白为Hb G Taipei:β22(B4)Glu→Gly。该变异体迄今仅见于我国汉族人群,在水族人群中系首次发现。
A slow hemoglobin was found in an aquarium family in Sandu Shui Autonomous County of Guizhou Province. Its electrophoresis behavior was similar to that of Hb G. The probands and other carriers were all heterozygotes with no clinical symptoms and hematological abnormalities. Chemical structure analysis identified this abnormal hemoglobin as Hb G Taipei: β22 (B4) Glu → Gly. The variant so far only found in Han Chinese population, the first discovery in the aquarium population.
