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]

The c.974C>T (p.T325M) alteration is located in exon 8 (coding exon 8) of the AGAP3 gene. This alteration results from a C to T substitution at nucleotide position 974, causing the threonine (T) at amino acid position 325 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
