Genes affected
GRIP2 (HGNC:23841): (glutamate receptor interacting protein 2) Predicted to enable protein C-terminus binding activity. Predicted to be involved in several processes, including neurotransmitter receptor transport, endosome to postsynaptic membrane; positive regulation of AMPA glutamate receptor clustering; and positive regulation of excitatory postsynaptic potential. Predicted to act upstream of or within Notch signaling pathway; artery smooth muscle contraction; and positive regulation of blood pressure. Predicted to be located in cytoplasm; dendritic shaft; and neuron spine. Predicted to be active in glutamatergic synapse and postsynaptic density.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2022The c.1120G>A (p.D374N) alteration is located in exon 9 (coding exon 9) of the GRIP2 gene. This alteration results from a G to A substitution at nucleotide position 1120, causing the aspartic acid (D) at amino acid position 374 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
