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

The c.3002T>A (p.V1001D) alteration is located in exon 27 (coding exon 26) of the TRAPPC11 gene. This alteration results from a T to A substitution at nucleotide position 3002, causing the valine (V) at amino acid position 1001 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

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

This sequence change replaces valine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 1001 of the TRAPPC11 protein (p.Val1001Asp). This variant is present in population databases (rs200989029, gnomAD 0.008%). 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: 541348). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). 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. -
