Genes affected

TNFRSF1A (HGNC:11916): (TNF receptor superfamily member 1A) This gene encodes a member of the TNF receptor superfamily of proteins. The encoded receptor is found in membrane-bound and soluble forms that interact with membrane-bound and soluble forms, respectively, of its ligand, tumor necrosis factor alpha. Binding of membrane-bound tumor necrosis factor alpha to the membrane-bound receptor induces receptor trimerization and activation, which plays a role in cell survival, apoptosis, and inflammation. Proteolytic processing of the encoded receptor results in release of the soluble form of the receptor, which can interact with free tumor necrosis factor alpha to inhibit inflammation. Mutations in this gene underlie tumor necrosis factor receptor-associated periodic syndrome (TRAPS), characterized by fever, abdominal pain and other features. Mutations in this gene may also be associated with multiple sclerosis in human patients. [provided by RefSeq, Sep 2016]

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.10964912 fraction of the gene. No cryptic splice site detected. Exon removal is inframe change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 12-6333366-C-T is Pathogenic according to our data. Variant chr12-6333366-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 97704.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr12-6333366-C-T is described in Lovd as [Pathogenic].

Significance: Likely pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant is predicted to disrupt the exon/intron 4 splice donor of TNFRSF1A. It has been described in the literature in a symptomatic proband and his also affected mother and was also functionally characterized (PMID: 18086728, 29467762): study data suggest this variant leads to an in-frame aberrant splicing resulting in deletion of Cys185 and insertion of 15 additional amino acids. The variant is also present in gnomAD once. Infevers classifies it as likely pathogenic. Internal data: heterozygous in a proband with suspected hereditary periodic fever syndrome. We classify it as likely pathogenic. -
