Genes affected

TRAF3IP2 (HGNC:1343): (TRAF3 interacting protein 2) This gene encodes a protein involved in regulating responses to cytokines by members of the Rel/NF-kappaB transcription factor family. These factors play a central role in innate immunity in response to pathogens, inflammatory signals and stress. This gene product interacts with TRAF proteins (tumor necrosis factor receptor-associated factors) and either I-kappaB kinase or MAP kinase to activate either NF-kappaB or Jun kinase. Several alternative transcripts encoding different isoforms have been identified. Another transcript, which does not encode a protein and is transcribed in the opposite orientation, has been identified. Overexpression of this transcript has been shown to reduce expression of at least one of the protein encoding transcripts, suggesting it has a regulatory role in the expression of this gene.

This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 231 of the TRAF3IP2 protein (p.Leu231Phe). This variant is present in population databases (rs149860754, gnomAD 0.06%). This missense change has been observed in individual(s) with psoriatic arthritis (PMID: 22513239). ClinVar contains an entry for this variant (Variation ID: 573542). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt TRAF3IP2 protein function. Experimental studies have shown that this missense change does not substantially affect TRAF3IP2 function (PMID: 22513239). 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. -
