Objective To investigate the incidence of neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD)in neonates with idiopathic neonatal cholestasis (INC)in Nanjing,China,SLC25A13 gene mutations in these neonates,and clinical features.Methods A total of 152 neonates with INC,who were admitted to the Affiliated Nanjing Children's Hospital of Nanjing Medical University from Sep-tember 2009 to August 2013,underwent gene analysis for detecting SLC25A13 gene mutations.The neonates were divided into NICCD group,who had been diagnosed definitely,and INC group at a ratio of 1∶2,considering the age and gender.Several biochemical indices were compared between the two groups.Comparison of continuous data between the two groups was made by Mann-Whitney U test after Bonferroni correction.Results There were 21 confirmed cases of NICCD (21/152,13.82%)among the 152 neonates with INC;five types of SLC25A13 mutations were identified in the 21 neonates with NICCD,including 851_854del (27/42,64.29%),IVS6+5 G→A (7/42, 16.67%),1638ins23 (5/42,11.90%),IVS11 +1 G→A (2/42,4.76%),and Q259X (1/42,2.38%).The alanine aminotransferase (ALT)level,aspartate aminotransferase (AST)level,bile acid concentration,albumin level,fasting blood glucose,blood ammonia,and prothrombin time for the NICCD group were 39.42 ±23.40 U/L,124.85 ±92.65 U/L,142.43 ±24.34μmol/L,30.66 ±2.70 g/L,2.79 ± 0.54 mmol/L,117.57 ±27.88 μmol/L,and 14.03 ±2.79 s,respectively,versus 136.02 ±113.67 U/L,226.12 ±129.26 U/L,80.47 ± 31.53 μmol/L,36.87 ±4.96 g/L,3.14 ±0.45 mmol/L,76.43 ±20.80 μmol/L,and 11.40 ±1.55 s for the INC group.The NICCD group had significantly lower ALT and AST levels than the INC group (Z=-5.02,P=0.000;Z=-3.66,P=0.000);the NICCD group had a significantly higher bile acid concentration than the INC group (Z=-5.58,P=0.000);the NICCD group had significantly lower albumin level and fasting blood glucose than the INC group (Z=-4.52,P=0.000;Z=-2.56,P=0.010);the NICCD group had a significantly higher blood ammonia level than the INC group (Z=-4.75,P=0.000);the NICCD group had a significantly longer prothrombin time than the INC group (Z=-4.10,P=0.000).Conclusion Citrin deficiency due to SLC25A13 gene mutations is an im-portant cause of INC in Nanjing.The three most common mutations are 851_854del,IVS6+5 G>A,and 1638_1660dup23,which account for 92.86% of the SLC25A13 gene mutations.More attention should be paid to clinical analysis and detection of SLC25A13 gene mutations to confirm the diagnosis of NICCD.
