Genes affected

SLC13A3 (HGNC:14430): (solute carrier family 13 member 3) Mammalian sodium-dicarboxylate cotransporters transport succinate and other Krebs cycle intermediates. They fall into 2 categories based on their substrate affinity: low affinity and high affinity. Both the low- and high-affinity transporters play an important role in the handling of citrate by the kidneys. The protein encoded by this gene represents the high-affinity form. Alternatively spliced transcript variants encoding different isoforms have been found for this gene, although the full-length nature of some of them have not been characterized yet.

This sequence change replaces tyrosine, which is neutral and polar, with serine, which is neutral and polar, at codon 583 of the SLC13A3 protein (p.Tyr583Ser). This variant is present in population databases (rs201204730, gnomAD 0.03%). 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. 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. This variant has not been reported in the literature in individuals affected with SLC13A3-related conditions. -
