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]

Uncertain significance, criteria provided, single submitter	clinical testing	Genome-Nilou Lab	Jul 15, 2021	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Oct 31, 2022	This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 251 of the SLC13A5 protein (p.Ala251Val). This variant is present in population databases (rs150517372, gnomAD 0.02%). 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: 569521). 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. -

The c.752C>T (p.A251V) alteration is located in exon 6 (coding exon 6) of the SLC13A5 gene. This alteration results from a C to T substitution at nucleotide position 752, causing the alanine (A) at amino acid position 251 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
