Genes affected

TNFRSF13B (HGNC:18153): (TNF receptor superfamily member 13B) The protein encoded by this gene is a lymphocyte-specific member of the tumor necrosis factor (TNF) receptor superfamily. It interacts with calcium-modulator and cyclophilin ligand (CAML). The protein induces activation of the transcription factors NFAT, AP1, and NF-kappa-B and plays a crucial role in humoral immunity by interacting with a TNF ligand. This gene is located within the Smith-Magenis syndrome region on chromosome 17. [provided by RefSeq, Jul 2008]

This sequence change replaces cysteine, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 193 of the TNFRSF13B protein (p.Cys193Arg). This variant is present in population databases (rs764125338, gnomAD 0.01%). This missense change has been observed in individual(s) with autoimmune lymphoproliferative syndrome and/or common variable immunodeficiency (PMID: 25569260, 33859323). ClinVar contains an entry for this variant (Variation ID: 449227). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt TNFRSF13B protein function with a negative predictive value of 95%. 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. -
