Genes affected
GRIK5 (HGNC:4583): (glutamate ionotropic receptor kainate type subunit 5) 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. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 20, 2024The c.2567G>A (p.R856H) alteration is located in exon 19 (coding exon 19) of the GRIK5 gene. This alteration results from a G to A substitution at nucleotide position 2567, causing the arginine (R) at amino acid position 856 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
