Genes affected
TRAF3IP1 (HGNC:17861): (TRAF3 interacting protein 1) The protein encoded by this gene interacts with TNF receptor-associated factor 3, tethering it to cytoskeletal microtubules. The encoded protein is also an inhibitor of the innate type I IFN response. Defects in this gene are a cause of Senior-Loken syndrome 9. [provided by RefSeq, Mar 2017]

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. This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 8 of the TRAF3IP1 protein (p.Arg8Trp). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with TRAF3IP1-related conditions. ClinVar contains an entry for this variant (Variation ID: 966360). 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 expected to disrupt TRAF3IP1 protein function. -
