Genes affected

CPLX2 (HGNC:2310): (complexin 2) 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. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]

The c.376G>A (p.G126R) alteration is located in exon 5 (coding exon 3) of the CPLX2 gene. This alteration results from a G to A substitution at nucleotide position 376, causing the glycine (G) at amino acid position 126 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
