A new splicing site substitution (c.985-1G>C) in the glucose-6-phosphate translocase (G6PT1) gene was detected in both alleles of an Argentinean patient. This mutation was associated with an unusual GSD-Ib phenotype without neutropenia. A PCR-based cDNA analysis showed that the c.985-1G>C mutation produced two abnormal spliced G6PT1 transcripts both encoding hypothetical truncated proteins.
在一名阿根廷患者的两个等位基因中均检测到葡萄糖-6-磷酸转运体(G6PT1)基因的一个新的剪接位点替代(c.985-1G>C)。该突变与一种无中性粒细胞减少的罕见糖原贮积病I型b(GSD-Ib)表型相关。基于PCR的cDNA分析表明,c.985-1G>C突变产生了两种异常剪接的G6PT1转录本,二者均编码假定的截短蛋白。
