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]

The c.541C>T (p.R181C) alteration is located in exon 7 (coding exon 6) of the SLC25A22 gene. This alteration results from a C to T substitution at nucleotide position 541, causing the arginine (R) at amino acid position 181 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 181 of the SLC25A22 protein (p.Arg181Cys). This variant is present in population databases (rs374216522, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with SLC25A22-related conditions. ClinVar contains an entry for this variant (Variation ID: 207176). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
