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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 16, 2024The c.1427C>T (p.P476L) alteration is located in exon 11 (coding exon 11) of the AGAP3 gene. This alteration results from a C to T substitution at nucleotide position 1427, causing the proline (P) at amino acid position 476 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
