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 sequence change creates a premature translational stop signal (p.Arg360*) in the SLC25A13 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SLC25A13 are known to be pathogenic (PMID: 10369257, 14680984, 27405544). This variant is present in population databases (rs80338721, gnomAD 0.01%). This premature translational stop signal has been observed in individuals with citrin deficiency (PMID: 18392553, 25365849). This variant is also known as c.1081C>T (p.R361X). ClinVar contains an entry for this variant (Variation ID: 21508). For these reasons, this variant has been classified as Pathogenic. -
