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 submitterclinical testingInvitaeFeb 06, 2020In 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, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with TRAPPC11-related conditions. ClinVar contains an entry for this variant (Variation ID: 448696). This variant is not present in population databases (ExAC no frequency). This sequence change replaces threonine with serine at codon 83 of the TRAPPC11 protein (p.Thr83Ser). The threonine residue is highly conserved and there is a small physicochemical difference between threonine and serine. -
