Genes affected

TRAF3 (HGNC:12033): (TNF receptor associated factor 3) The protein encoded by this gene is a member of the TNF receptor associated factor (TRAF) protein family. TRAF proteins associate with, and mediate the signal transduction from, members of the TNF receptor (TNFR) superfamily. This protein participates in the signal transduction of CD40, a TNFR family member important for the activation of the immune response. This protein is found to be a critical component of the lymphotoxin-beta receptor (LTbetaR) signaling complex, which induces NF-kappaB activation and cell death initiated by LTbeta ligation. Epstein-Barr virus encoded latent infection membrane protein-1 (LMP1) can interact with this and several other members of the TRAF family, which may be essential for the oncogenic effects of LMP1. The protein also plays a role in the regulation of antiviral response. Mutations in this are associated with Encephalopathy, acute, infection-induced, herpes-specific 5.

ACMG classification

Verdict is Likely_benign. Variant got -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), TRAF3. . Gene score misZ 2.9892 (greater than the threshold 3.09). Trascript score misZ 4.4099 (greater than threshold 3.09). GenCC has associacion of gene with TRAF3 haploinsufficiency.
• BP4: Computational evidence support a benign effect (MetaRNN=0.057887048).

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. 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 TRAF3-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces proline with threonine at codon 10 of the TRAF3 protein (p.Pro10Thr). The proline residue is weakly conserved and there is a small physicochemical difference between proline and threonine. -
