Genes affected

SLC1A2 (HGNC:10940): (solute carrier family 1 member 2) This gene encodes a member of a family of solute transporter proteins. The membrane-bound protein is the principal transporter that clears the excitatory neurotransmitter glutamate from the extracellular space at synapses in the central nervous system. Glutamate clearance is necessary for proper synaptic activation and to prevent neuronal damage from excessive activation of glutamate receptors. Improper regulation of this gene is thought to be associated with several neurological disorders. Alternatively spliced transcript variants of this gene have been identified.

The c.1687T>A (p.C563S) alteration is located in exon 11 (coding exon 11) of the SLC1A2 gene. This alteration results from a T to A substitution at nucleotide position 1687, causing the cysteine (C) at amino acid position 563 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces cysteine, which is neutral and slightly polar, with serine, which is neutral and polar, at codon 563 of the SLC1A2 protein (p.Cys563Ser). This variant is present in population databases (rs201454950, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with SLC1A2-related conditions. ClinVar contains an entry for this variant (Variation ID: 1362190). 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. -
