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 sequence change replaces glycine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 104 of the CPLX1 protein (p.Gly104Asp). This variant is present in population databases (rs562631127, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with CPLX1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1411489). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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. -
