Genes affected
SLC13A5 (HGNC:23089): (solute carrier family 13 member 5) This gene encodes a protein belonging to the solute carrier family 13 group of proteins. This family member is a sodium-dependent citrate cotransporter that may regulate metabolic processes. Mutations in this gene cause early infantile epileptic encephalopathy 25. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2014]

Submissions by phenotype

Developmental and epileptic encephalopathy, 25 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 02, 2022Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on SLC13A5 protein function. ClinVar contains an entry for this variant (Variation ID: 581306). This variant has not been reported in the literature in individuals affected with SLC13A5-related conditions. This variant is present in population databases (rs138841868, gnomAD 0.007%). This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 315 of the SLC13A5 protein (p.Ala315Val). 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. -
