Genes affected
SLC25A13 (HGNC:10983): (solute carrier family 25 member 13) This gene is a member of the mitochondrial carrier family. The encoded protein contains four EF-hand Ca(2+) binding motifs in the N-terminal domain, and localizes to mitochondria. The protein catalyzes the exchange of aspartate for glutamate and a proton across the inner mitochondrial membrane, and is stimulated by calcium on the external side of the inner mitochondrial membrane. Mutations in this gene result in citrullinemia, type II. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2009]

Pathogenic, criteria provided, single submitterclinical testingInvitaeApr 15, 2023This variant is present in population databases (rs80338726, gnomAD 0.02%). For these reasons, this variant has been classified as Pathogenic. This variant disrupts the C-terminus of the SLC25A13 protein. Other variant(s) that disrupt this region (p.Arg605*, p.Glu601*) have been observed in individuals with SLC25A13-related conditions (PMID: 11153906, 11793471). This suggests that this may be a clinically significant region of the protein. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. ClinVar contains an entry for this variant (Variation ID: 6006). This variant is also known as Mutation VI, 1800ins1. This premature translational stop signal has been observed in individuals with citrin deficiency (PMID: 11153906, 11343052). This sequence change creates a premature translational stop signal (p.Tyr600*) in the SLC25A13 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 76 amino acid(s) of the SLC25A13 protein. -
