Genes affected

TRAPPC9 (HGNC:30832): (trafficking protein particle complex subunit 9) This gene encodes a protein that likely plays a role in NF-kappa-B signaling. Mutations in this gene have been associated with autosomal-recessive cognitive disability. Alternatively spliced transcript variants have been described.[provided by RefSeq, Feb 2010]

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 126 of the TRAPPC9 protein (p.Glu126Lys). This variant is present in population databases (rs151056818, gnomAD 0.07%). This variant has not been reported in the literature in individuals affected with TRAPPC9-related conditions. ClinVar contains an entry for this variant (Variation ID: 437041). 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: "Not Available"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Not Available"). 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. -
