Genes affected
SLC25A22 (HGNC:19954): (solute carrier family 25 member 22) This gene encodes a mitochondrial glutamate carrier. Mutations in this gene are associated with early infantile epileptic encephalopathy. Multiple alternatively spliced variants, encoding the same protein, have been identified.[provided by RefSeq, Jul 2010]

Submissions by phenotype
Early infantile epileptic encephalopathy with suppression bursts Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Sep 13, 2022 | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 212198). This variant has not been reported in the literature in individuals affected with SLC25A22-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Gln140*) in the SLC25A22 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SLC25A22 are known to be pathogenic (PMID: 15592994, 19780765). - |
not provided Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | GeneDx | Mar 25, 2021 | Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss-of-function is a known mechanism of disease; Not observed in large population cohorts (Lek et al., 2016); Has not been previously published as pathogenic or benign to our knowledge - |
