Genes affected

TNFAIP3 (HGNC:11896): (TNF alpha induced protein 3) This gene was identified as a gene whose expression is rapidly induced by the tumor necrosis factor (TNF). The protein encoded by this gene is a zinc finger protein and ubiqitin-editing enzyme, and has been shown to inhibit NF-kappa B activation as well as TNF-mediated apoptosis. The encoded protein, which has both ubiquitin ligase and deubiquitinase activities, is involved in the cytokine-mediated immune and inflammatory responses. Several transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2012]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.061516374).

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000226 (33/1461878) while in subpopulation SAS AF = 0.000371 (32/86256). AF 95% confidence interval is 0.00027. There are 1 homozygotes in GnomAdExome4. There are 21 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAdExome4 at 33 Unknown,AD gene.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 551 of the TNFAIP3 protein (p.Leu551Phe). This variant is present in population databases (rs587778712, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with TNFAIP3-related conditions. ClinVar contains an entry for this variant (Variation ID: 135339). 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 tolerated. 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. -
