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]

Developmental and epileptic encephalopathy, 25 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | May 07, 2022 | This sequence change replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 564 of the SLC13A5 protein (p.Thr564Ile). This variant is present in population databases (rs771551520, gnomAD 0.0009%). 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: 1014097). 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. - |
