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]

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 22, 2024 | This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1059 of the TRAPPC9 protein (p.Ala1059Val). This variant is present in population databases (rs769398594, gnomAD 0.02%). 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: 212426). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. - |

Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 02, 2018 | The p.A1059V variant (also known as c.3176C>T), located in coding exon 20 of the TRAPPC9 gene, results from a C to T substitution at nucleotide position 3176. The alanine at codon 1059 is replaced by valine, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this variant remains unclear. - |
