Genes affected
GRID1 (HGNC:4575): (glutamate ionotropic receptor delta type subunit 1) This gene encodes a subunit of glutamate receptor channels. These channels mediate most of the fast excitatory synaptic transmission in the central nervous system and play key roles in synaptic plasticity.[provided by RefSeq, Jan 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 18, 2024The c.2075G>A (p.R692Q) alteration is located in exon 13 (coding exon 13) of the GRID1 gene. This alteration results from a G to A substitution at nucleotide position 2075, causing the arginine (R) at amino acid position 692 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
