Genes affected

AGAP3 (HGNC:16923): (ArfGAP with GTPase domain, ankyrin repeat and PH domain 3) This gene encodes an essential component of the N-methyl-D-aspartate (NMDA) receptor signaling complex which mediates long-term potentiation in synapses by linking activation of NMDA receptor to alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor trafficking. The encoded protein contains an N-terminal GTPase-like domain, a pleckstrin homology domain, an ArfGAP domain and several C-terminal ankryn repeat domains. [provided by RefSeq, Apr 2017]

Ambry Genetics

Sep 17, 2021

The c.516G>T (p.Q172H) alteration is located in exon 4 (coding exon 4) of the AGAP3 gene. This alteration results from a G to T substitution at nucleotide position 516, causing the glutamine (Q) at amino acid position 172 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
