Genes affected

GRIK4 (HGNC:4582): (glutamate ionotropic receptor kainate type subunit 4) This gene encodes a protein that belongs to the glutamate-gated ionic channel family. Glutamate functions as the major excitatory neurotransmitter in the central nervous system through activation of ligand-gated ion channels and G protein-coupled membrane receptors. The protein encoded by this gene forms functional heteromeric kainate-preferring ionic channels with the subunits encoded by related gene family members. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2013]

The c.602C>T (p.T201I) alteration is located in exon 5 (coding exon 5) of the GRIK4 gene. This alteration results from a C to T substitution at nucleotide position 602, causing the threonine (T) at amino acid position 201 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
