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.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 27, 2021The c.271G>A (p.E91K) alteration is located in exon 4 (coding exon 3) of the CPLX1 gene. This alteration results from a G to A substitution at nucleotide position 271, causing the glutamic acid (E) at amino acid position 91 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
