Genes affected

CPLX1 (HGNC:2309): (complexin 1) Proteins encoded by the complexin/synaphin gene family are cytosolic proteins that function in synaptic vesicle exocytosis. These proteins bind syntaxin, part of the SNAP receptor. The protein product of this gene binds to the SNAP receptor complex and disrupts it, allowing transmitter release.

Feb 17, 2022

The c.274G>T (p.G92W) alteration is located in exon 4 (coding exon 3) of the CPLX1 gene. This alteration results from a G to T substitution at nucleotide position 274, causing the glycine (G) at amino acid position 92 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
