Genes affected

SLC25A1 (HGNC:10979): (solute carrier family 25 member 1) This gene encodes a member of the mitochondrial carrier subfamily of solute carrier proteins. Members of this family include nuclear-encoded transporters that translocate small metabolites across the mitochondrial membrane. This protein regulates the movement of citrate across the inner membranes of the mitochondria. Mutations in this gene have been associated with combined D-2- and L-2-hydroxyglutaric aciduria. Pseudogenes of this gene have been identified on chromosomes 7, 11, 16, and 19. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2013]

Pathogenic:2

Likely pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Oct 11, 2021	In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant disrupts the p.Arg282 amino acid residue in SLC25A1. Other variant(s) that disrupt this residue have been observed in individuals with SLC25A1-related conditions (PMID: 23393310, 23561848, 29238895), which suggests that this may be a clinically significant amino acid residue. Experimental studies have shown that this missense change affects SLC25A1 function (PMID: 9031613, 29238895). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 42194). This missense change has been observed in individuals with combined D-2- and L-2-hydroxyglutaric aciduria (PMID: 23561848, 29238895). This variant is present in population databases (rs431905509, ExAC 0.005%). This sequence change replaces arginine with cysteine at codon 282 of the SLC25A1 protein (p.Arg282Cys). The arginine residue is highly conserved and there is a large physicochemical difference between arginine and cysteine. -
Pathogenic, criteria provided, single submitter	clinical testing	GeneDx	Mar 21, 2023	Published functional studies demonstrate a damaging effect on enzyme activity (Pop et al., 2018; Majd et al., 2018); Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 29238895, 23561848, 34930662, 29031613) -
