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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.009047955).

BS1

Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0000723 (11/152178) while in subpopulation EAS AF= 0.00193 (10/5194). AF 95% confidence interval is 0.00104. There are 0 homozygotes in gnomad4. There are 5 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 453 of the TRAF3IP1 protein (p.Ser453Cys). This variant is present in population databases (rs146820102, gnomAD 0.3%). This missense change has been observed in individual(s) with asphyxiating thoracic dystrophy (PMID: 29068549). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 446658). 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 TRAF3IP1 protein function. 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. -
