Abstract:Objective To investigate the mutation and biochemical characteristics of SLC25A13 gene in neonatal intrahepatic cholestasis caused by Citrin protein deficiency (NICCD)in Tujia minority in Zhangjiajie Area.Methods SLC25A13 gene mutation analysis was performed in children with idiopathic neonatal cholestasis(INC)admitted to the Department of Pediatrics in our Hospital from September 2014 to December 2016.The patients diagnosed with NICCD were classified into observation group.Pediatric patients randomly selected except for NICCD were assigned to control group.The differences in biochemical indicators between the two groups were compared.Results Among 85 pediatric patients performed with SLC25A13 gene mutation analysis,7 cases were diagnosed as NICCD.The SLC25A13 gene mutated for three mutations including 1851del4,IVS6+5G>A,and 1638ins23,of which the 1851del4 mutation accounted for 57.10%of the total mutations.The comparison of biochemical indicators showed that the total bile acid,gammaglutamyl transpeptidase,prothrombin time,and aspartate aminotransferase/alanine aminotransferase (AST/ALT)were higher in the observation group than in the control group,and the levels of ALT,AST,serum albumin,and BS were lower in the observation group than in the control group(P<0.05).Conclusion NICCD due to SLC25A13 gene mutation is one of the main causes for INC in Tujia minority in Zhangjiajie Area.The 1851del4 mutant is the most common type.Changes in biochemical markers in NICCD children are helpful for early identification of the disease.
