摘要：

Adult-onset type II citrullinemia (CTLN2), characterized by a liver-specific deficiency of urea cycle enzyme, argininosuccinate synthetase, is caused by mutations in SLC25A13 that encodes a calcium binding mitochondrial solute carrier protein, citrin. Citrin deficiency causes not only CTLN2 but also neonatal intrahepatic cholestasis caused by citrin deficiency at neonatal period. Moreover citrin and its isoform aralar were found to be aspartate glutamate carrier. From the viewpoint of the metabolic functions of citrin as aspartate glutamate carrier in urea synthesis and NADH shuttle, symptoms of CTLN2 and neonatal intrahepatic cholestasis caused by citrin deficiency are analyzed.
