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]

The L96P variant has been reported previously, using alternate nomenclature, in a family with features of TRAPS, including fevers, abdominal pain, and urticaria (Dode et al., 2002). The L96P variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. In silico analysis predicts this variant is probably damaging to the protein structure/function. Missense mutations in nearby residues (N94I, H95L/Y) have been reported in the Human Gene Mutation Database in association with TNFRSF1A-related disorders (Stenson et al., 2009), supporting the functional importance of this region of the protein. The L96P variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is moderately conserved across species. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic mutation or a rare benign variant. -
