Abstract

A follow-up over 7 years on a patient with congenital disorder of glycosylation type Ia showed a significant normalization of hypoglycosylated transferrin. Isoelectric focusing for serum transferrin is a widely used screening method but there could be a limit of detection and the subtle changes can be also overlooked. Re-test with a different method is desirable, especially when the clinical suspicion for congenital disorder of glycosylation is high.

摘要

对一名Ia型先天性糖基化障碍患者进行的7年随访显示,低糖化转铁蛋白显著恢复正常。血清转铁蛋白的等电聚焦是一种广泛使用的筛查方法,但可能存在检测限,细微变化也可能被忽视。尤其是当临床高度怀疑先天性糖基化障碍时,采用不同方法重新检测是可取的。
