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]

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	Feb 23, 2020	The TNFRSF1A c.323-3C>G variant (rs1328399119), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 463376). This variant is found on only four chromosomes in the Genome Aggregation Database (4/282678 alleles), indicating it is not a common polymorphism. This is an intronic variant in a moderately conserved nucleotide, and computational analyses (Alamut v.2.11) predict that this variant may impact splicing by weakening the nearby canonical acceptor splice site. However, RNA studies would be required to confirm these predictions. Given the lack of clinical and functional data, the significance of the c.323-3C>G variant is uncertain at this time. -

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. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 463376). This variant has not been reported in the literature in individuals affected with TNFRSF1A-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change falls in intron 3 of the TNFRSF1A gene. It does not directly change the encoded amino acid sequence of the TNFRSF1A protein. It affects a nucleotide within the consensus splice site. -
