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.

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 output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The histidine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 2157513). This variant has not been reported in the literature in individuals affected with SLC1A2-related conditions. This variant is present in population databases (rs766885690, gnomAD 0.03%). This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 572 of the SLC1A2 protein (p.Arg572His). -
