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 GeneticsJun 02, 2023The c.1774C>T (p.P592S) alteration is located in exon 13 (coding exon 13) of the GRIP2 gene. This alteration results from a C to T substitution at nucleotide position 1774, causing the proline (P) at amino acid position 592 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
