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.

This variant, c.339_341dup, results in the insertion of 1 amino acid(s) of the CPLX1 protein (p.Asp113dup), but otherwise preserves the integrity of the reading frame. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant has not been reported in the literature in individuals affected with CPLX1-related conditions. This variant is present in population databases (rs746146625, gnomAD 0.002%). -
