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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 27, 2023The c.350T>C (p.L117P) alteration is located in exon 5 (coding exon 3) of the CPLX2 gene. This alteration results from a T to C substitution at nucleotide position 350, causing the leucine (L) at amino acid position 117 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
