Interaction Information:

Comment Citrullinemia is an autosomal recessive disorder of the urea cycle. Citrullinemia type 1 (classical type) is caused through mutations in the CTLN1 gene encoding argininosuccinate synthase. Citrullinemia type 2 is caused through mutations in the liver-type isoform of SLC25A13 gene (called citrin) encoding an aspartate/glutamate carrier. SLC25A13 supplies aspartate to ASS1 (CTLN1).
