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]

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. 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 tolerated. ClinVar contains an entry for this variant (Variation ID: 474353). This variant has not been reported in the literature in individuals affected with TRAPPC11-related conditions. This variant is present in population databases (rs200931036, gnomAD 0.02%). This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 895 of the TRAPPC11 protein (p.Val895Ala). -
