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 GeneticsJan 31, 2024The c.1465T>C (p.F489L) alteration is located in exon 12 (coding exon 12) of the GRIP2 gene. This alteration results from a T to C substitution at nucleotide position 1465, causing the phenylalanine (F) at amino acid position 489 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
