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]

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

Has not been previously published as pathogenic or benign to our knowledge; In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function -

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

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. ClinVar contains an entry for this variant (Variation ID: 474364). This variant has not been reported in the literature in individuals affected with TRAPPC11-related conditions. This variant is present in population databases (rs147061560, gnomAD 0.05%). This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 1072 of the TRAPPC11 protein (p.Thr1072Met). -
