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 Pathogenic. Variant got 12 ACMG points.

• PM1: In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 7 uncertain in NM_001065.4
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr12-6334109-A-G is described in ClinVar as [Pathogenic]. Clinvar id is 12337.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.961
• PP5: Variant 12-6334108-C-G is Pathogenic according to our data. Variant chr12-6334108-C-G is described in ClinVar as [Pathogenic]. Clinvar id is 12342.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr12-6334108-C-G is described in Lovd as [Pathogenic].

Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Sep 09, 2020	For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Cys59 amino acid residue in TNFRSF1A. Other variant(s) that disrupt this residue have been observed in individuals with TNFRSF1A-related conditions (PMID: 11722598, 15216558, 18408954, 10199409), which suggests that this may be a clinically significant amino acid residue. This variant has been reported to affect TNFRSF1A protein function (PMID: 16684962). This variant has been observed in several individuals and families affected with TNF receptor-associated periodic syndrome (TRAPS) (PMID: 10902757, 20576331, 11443543). This variant is also known as p.C30S in the literature. ClinVar contains an entry for this variant (Variation ID: 12342). This variant is present in population databases (rs104895223, ExAC 0.01%). This sequence change replaces cysteine with serine at codon 59 of the TNFRSF1A protein (p.Cys59Ser). The cysteine residue is highly conserved and there is a moderate physicochemical difference between cysteine and serine. -
