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]
SLC1A3-AS1 (HGNC:56374): (SLC1A3 antisense RNA 1)

This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 205 of the SLC1A3 protein (p.Ala205Thr). This variant is present in population databases (rs747247810, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with SLC1A3-related conditions. ClinVar contains an entry for this variant (Variation ID: 586621). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests 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. -
