About SYNGAP1

Cytogenetic location: 6p21.32 Genomic coordinates (GRCh38): 6:33,418,167-33,453,689 (from NCBI)

This gene has 30 transcripts (splice variants), 1 gene allele, 279 orthologues, 10 paralogues and is associated with 6 phenotypes. Ubiquitous expression in brain (RPKM 17.6), ovary (RPKM 8.3) and 23 other tissues.

Summary

This gene encodes a Ras GTPase activating protein that is a member of the N-methyl-D-aspartate receptor complex. The N-terminal domain of the protein contains a Ras-GAP domain, a pleckstrin homology domain, and a C2 domain that may be involved in binding of calcium and Phospholipids. The C-terminal domain consists of a ten histidine repeat region, serine and tyrosine phosphorylation sites, and a T/SXV motif required for postsynaptic scaffold protein interaction. The encoded protein negatively regulates Ras, Rap and alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor trafficking to the postsynaptic membrane to regulate synaptic plasticity and neuronal homeostasis. Allelic variants of this gene are associated with intellectual disability and autism spectrum disorder. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2016]
