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:2
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 08, 2022This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 201 of the SLC13A5 protein (p.Arg201Gln). This variant is present in population databases (rs200275193, gnomAD 0.07%). This variant has not been reported in the literature in individuals affected with SLC13A5-related conditions. ClinVar contains an entry for this variant (Variation ID: 475200). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SLC13A5 protein function. 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. -

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 11, 2021The c.602G>A (p.R201Q) alteration is located in exon 5 (coding exon 5) of the SLC13A5 gene. This alteration results from a G to A substitution at nucleotide position 602, causing the arginine (R) at amino acid position 201 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
