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.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. This variant is present in population databases (rs80338726, gnomAD 0.02%). This premature translational stop signal has been observed in individuals with citrin deficiency (PMID: 11153906, 11343052). This variant is also known as Mutation VI, 1800ins1. ClinVar contains an entry for this variant (Variation ID: 6006). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. For these reasons, this variant has been classified as Pathogenic. -

The SLC25A13 c.1799dupA variant is predicted to result in premature protein termination (p.Tyr600*). This variant was reported along with a second SLC25A13 variant in at least two individuals with citrullinaemia, type II (described as [VI] 1800ins1 in Yasuda et al 2000. PubMed ID: 11153906; described as mutation VI in Tazawa et al. 2001. PubMed ID: 11343052). Citrin protein was found to be absent in a liver sample from the patient described by Yasuda et al. (see Figure 4, Yasuda et al 2000. PubMed ID: 11153906). This variant is reported in 0.017% of alleles in individuals of Latino descent in gnomAD. Nonsense variants in SLC25A13 are expected to be pathogenic. Taken together, this variant is interpreted as pathogenic. -
