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]
C17orf100 (HGNC:34494): (chromosome 17 open reading frame 100)

Submissions by phenotype

Developmental and epileptic encephalopathy, 25 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeAug 19, 2022This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 445 of the SLC13A5 protein (p.Pro445Leu). This variant is present in population databases (rs558866003, gnomAD 0.06%). 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: 541962). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. -
