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]

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

The SLC25A13 c.1505C>T variant is predicted to result in the amino acid substitution p.Pro502Leu. This variant has been reported in a patient with questionable diagnosis of neonatal intrahepatic cholestasis and was shown in functional studies to be fully functional (Wongkittichote et al. 2013. PubMed ID: 21507300; Wen et al. 2011. PubMed ID: 23053473). This variant is reported in 0.17% to 0.20% of alleles, including one homozygous, in individuals of Ashkenazi Jewish descent in gnomAD datasets. Although we suspect that this variant may be benign, the clinical significance of this variant is classified as uncertain at this time due to insufficient functional and genetic evidence. -
