Abstract

A new unstable α-globin variant was detected in a child with hypoxemia and anemia. The child's mother was found to carry the same mutation. The hemoglobin (Hb) variant co-eluted with Hb A(2) by cation exchange high performance liquid chromatography (HPLC) and appeared cathodal to Hb A and anodal to Hb F by isoelectric focusing. It represented less than 20% of the total Hb and was unstable by isopropanol testing. Gene sequencing identified a missense mutation on the α2 gene [HBA2:c.140T>C]. Oxygen dissociation and P(50) test results were normal.

摘要

在一名患有低氧血症和贫血的儿童中检测到一种新的不稳定α-珠蛋白变体。发现该儿童的母亲携带相同的突变。通过阳离子交换高效液相色谱法(HPLC),血红蛋白(Hb)变体与Hb A(2) 共同洗脱,并且在等电聚焦时出现在Hb A的阴极侧和Hb F的阳极侧。它占总Hb的比例不到20%,并且通过异丙醇试验显示不稳定。基因测序确定α2基因上存在一个错义突变 [HBA2:c.140T>C]。氧解离和P(50)测试结果正常。
