Genes affected

GRIK3 (HGNC:4581): (glutamate ionotropic receptor kainate type subunit 3) Glutamate receptors are the predominant excitatory neurotransmitter receptors in the mammalian brain and are activated in a variety of normal neurophysiologic processes. This gene product belongs to the kainate family of glutamate receptors, which are composed of four subunits and function as ligand-activated ion channels. It is not certain if the subunit encoded by this gene is subject to RNA editing as the other 2 family members (GRIK1 and GRIK2). A Ser310Ala polymorphism has been associated with schizophrenia, and there are conflicting reports of its association with the pathogenesis of delirium tremens in alcoholics.

Ambry Genetics

Sep 30, 2024

The c.1701G>A (p.M567I) alteration is located in exon 11 (coding exon 11) of the GRIK3 gene. This alteration results from a G to A substitution at nucleotide position 1701, causing the methionine (M) at amino acid position 567 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
