Glycogen storage disease type IV (GSD-IV) is an autosomal recessive disease caused by a deficient glycogen branching enzyme (GBE), encoded by the GBE1 gene, resulting in the accumulation of abnormal glycogen deposits in the liver and other tissues. We treated a 20-month-old girl who presented with progressive liver cirrhosis and was diagnosed with GSD-IV, as confirmed by GBE1 gene mutation analysis, and underwent living related heterozygous donor liver transplantation. Direct sequencing of the GBE1 gene revealed that the patient was compound heterozygous for a known c.1571G>A (p.Gly264Glu) mutation a novel c.791G>A (Arg524Gln) mutation. This is the first report of a Korean patient with GSD-IV confirmed by mutation analysis, who was treated successfully by liver transplantation.
糖原贮积病Ⅳ型(GSD-IV)是一种常染色体隐性遗传病,由糖原分支酶(GBE)缺乏引起,该酶由 GBE1 基因编码,导致肝脏和其他组织中异常糖原沉积的积累。我们治疗了一名 20 个月大的女孩,她因进行性肝硬化就诊,并通过 GBE1 基因突变分析确诊为 GSD-IV,并接受了活体相关杂合供体肝移植。GBE1 基因的直接测序显示,患者为已知的 c.1571G>A(p.Gly264Glu)突变的复合杂合子,以及新的 c.791G>A(Arg524Gln)突变。这是首例通过突变分析证实的韩国 GSD-IV 患者的报告,该患者通过肝移植成功治疗。
