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]

Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Feb 01, 2023	Identified in the heterozygous state and with a second variant in TNFRSF13B in patients with common variable immune deficiency (Pulvirenti et al., 2016; Rojas-Restrepo et al., 2021); Nonsense variant predicted to result in protein truncation, as the last 58 amino acids are lost, and other loss-of-function variants have been reported downstream in HGMD.; This variant is associated with the following publications: (PMID: 26284228, 25205549, 36155879, 31150062, 27123465, 34441032, 34975878) -

This sequence change creates a premature translational stop signal (p.Glu236*) in the TNFRSF13B gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 58 amino acid(s) of the TNFRSF13B protein. This variant is present in population databases (rs201021960, gnomAD 0.3%). This premature translational stop signal has been observed in individual(s) with antibody deficiency and/or common variable immune deficiency (CVID) and pancreatic cancer (PMID: 27123465, 34975878). ClinVar contains an entry for this variant (Variation ID: 538709). Studies have shown that this premature translational stop signal does not significantly alter or has an unclear effect on TNFRSF13B gene expression (PMID: 25205549). 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. -
