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]

Uncertain significance, criteria provided, single submitter	clinical testing	Revvity Omics, Revvity	Oct 02, 2020	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Aug 16, 2022	This sequence change replaces serine, which is neutral and polar, with tyrosine, which is neutral and polar, at codon 407 of the TRAPPC11 protein (p.Ser407Tyr). This variant is present in population databases (rs375379302, gnomAD 0.01%). 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: 474344). 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: "Possibly Damaging"; Align-GVGD: "Class C15"). 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. -
