Abstract: Crigler-Najjar Syndrome (CNS) is congenital, non-obstructive, non-hemolytic, hyperunbound bilirubinemia, which is characterized by a completed or near-total deficiency of uridine diphosphate glucuronosyl transferase 1A1 (UGT1A1) in liver cells.The preliminary diagnosis of CNS is mainly based on clinical manifestations and laboratory examination.After that, the diagnosis can be made by combining genetic testing, analysis of bile components and determination of UGT1A1 activity in liver tissues.CNS and UGT1A1 gene polymorphisms are of great significance in the metabolism of multiple drugs and the pathogenesis of multiple diseases.Even if the mechanism and specific effects of the genes are not qualitatively and quantitatively evaluated, clear diagnosis is of great significance for clinical guidance.This review summarizes the clinical diagnosis and treatment of CNS and the relationship between UGT1A1 gene mutations and CNS.

摘要: Crigler-Najjar综合征(CNS)是先天性、非梗阻性、非溶血性、高未结合胆红素血症。其特征是肝细胞完全或接近完全缺乏尿嘧啶二磷酸葡萄糖醛基转移酶1A1(UGT1A1)。CNS的诊断主要是根据临床表现及实验室检查初步诊断, 之后可结合基因检测、胆汁成分分析、肝组织中UGT1A1酶活性测定等方法进行确诊。CNS及UGT1A1基因多态性在多种药物代谢及多种疾病的发病中有重要的意义, 即使其作用机制及具体影响没有一个定性及定量的评定, 但明确诊断后对于临床的指导意义很大。本文就CNS的临床诊治以及UGT1A1基因突变之间的关系进行综述。
