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.

Ambry Genetics

Nov 30, 2021

The c.2279G>T (p.G760V) alteration is located in exon 18 (coding exon 18) of the GRIP2 gene. This alteration results from a G to T substitution at nucleotide position 2279, causing the glycine (G) at amino acid position 760 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
