Genes affected

SLC1A3 (HGNC:10941): (solute carrier family 1 member 3) This gene encodes a member of a member of a high affinity glutamate transporter family. This gene functions in the termination of excitatory neurotransmission in central nervous system. Mutations are associated with episodic ataxia, Type 6. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Feb 2014]

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 499 of the SLC1A3 protein (p.Arg499Gln). This variant is present in population databases (rs138085358, gnomAD 0.01%). This missense change has been observed in individual(s) with ataxia (PMID: 25497598). This variant is also known as Arg454Gln. ClinVar contains an entry for this variant (Variation ID: 242994). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt SLC1A3 protein function with a negative predictive value of 80%. Studies have shown that this missense change alters SLC1A3 gene expression (PMID: 32741053). 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. -
