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 testingNeuberg Centre For Genomic Medicine, NCGM-The stop gained variant c.550C>T (p.Arg184Ter) in SLC25A13 gene has been observed in individuals affected with citrin deficiency (Lin et al. 2016). This sequence change creates a premature translational stop signal (p.Arg184*) in the SLC25A13 gene. It is expected to result in an absent or disrupted protein product. This variant has been reported to the ClinVar database as Pathogenic. The variant is novel (not in any individuals) in 1000 Genomes. This variant is present in ExAC population database with a frequency of 0.006%. Loss-of-function variants in SLC25A13 are known to be pathogenic (Kobayashi et al. 2003, Lin et al. 2016). The nucleotide change in SLC25A13 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Pathogenic -
