Genes affected

TRAPPC11 (HGNC:25751): (trafficking protein particle complex subunit 11) The protein encoded by this gene is a subunit of the TRAPP (transport protein particle) tethering complex, which functions in intracellular vesicle trafficking. This subunit is involved in early stage endoplasmic reticulum-to-Golgi vesicle transport. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jan 2013]

This sequence change replaces alanine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 325 of the TRAPPC11 protein (p.Ala325Asp). This variant is present in population databases (rs775652273, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with TRAPPC11-related conditions. ClinVar contains an entry for this variant (Variation ID: 474370). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt TRAPPC11 protein function. 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. -
