Identified in the heterozygous state and with a second variant in TNFRSF13B in patients with common variable immune deficiency (PMID: 27123465, 34975878); 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, 34441032, 34975878, 27123465) -
Immunodeficiency, common variable, 2 Uncertain:1
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. -
