摘要 目的探讨新生儿型氨甲酰磷酸合成酶Ⅰ缺乏症(CPSⅠD)的临床特点及实验室分析结果。方法收集1例CPSⅠD患者的临床资料及基因测序结果,并结合相关文献进行分析。结果患儿出生2 d即出现吮奶差,随后出现精神反应差,拒奶,嗜睡,昏迷和高氨血症,1个月后开始出现贫血;患儿外周血及其父母外周血染色体核型均显示正常,基因测序结果显示患儿为2个CPSⅠ基因变异,均位于2号染色体,分别源于父方和母方,其中c.2359(exon19)C>T是致病突变位点,c.3389(exon27)C>A基因突变位点临床意义不明;地中海贫血血红蛋白电泳检测结果Bart′s2.9,基因型诊断为SEA杂合,血串联质谱瓜氨酸显著降低。结论新生儿疾病筛查技术结合基因测序有利于疾病的早发现早诊断,新生儿起病迅速,常规治疗未见明显改善时应高度怀疑遗传代谢性疾病,并进行相应的筛查和精准确诊。
