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 GeneticsApr 23, 2024The c.2788G>T (p.V930L) alteration is located in exon 19 (coding exon 19) of the GRIK5 gene. This alteration results from a G to T substitution at nucleotide position 2788, causing the valine (V) at amino acid position 930 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
