Genes affected
RAPGEF4 (HGNC:16626): (Rap guanine nucleotide exchange factor 4) Enables guanyl-nucleotide exchange factor activity. Predicted to be involved in regulation of neurotransmitter receptor localization to postsynaptic specialization membrane and regulation of postsynapse organization. Predicted to act upstream of or within adenylate cyclase-activating G protein-coupled receptor signaling pathway; regulation of exocytosis; and secretion by cell. Predicted to be located in plasma membrane. Predicted to be active in glutamatergic synapse; hippocampal mossy fiber to CA3 synapse; and postsynaptic density. Implicated in autistic disorder.

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 30, 2023 | The c.1671G>C (p.Q557H) alteration is located in exon 18 (coding exon 18) of the RAPGEF4 gene. This alteration results from a G to C substitution at nucleotide position 1671, causing the glutamine (Q) at amino acid position 557 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
