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 creates a premature translational stop signal (p.Ser144*) in the TNFRSF13B gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TNFRSF13B are known to be pathogenic (PMID: 16007087, 27123465). This variant is present in population databases (rs104894650, gnomAD 0.009%). This premature translational stop signal has been observed in individual(s) with autoimmune lymphoproliferative syndrome and common variable immunodeficiency (PMID: 25569260, 27123465). ClinVar contains an entry for this variant (Variation ID: 265340). For these reasons, this variant has been classified as Pathogenic. -

Identified with two other TNFRSF13B variants in a patient with common variable immunodeficiency disorder, however, it is unclear if parental segregation studies were done to confirm the phase of these variants (Pulvirenti et al., 2016); Identified in the heterozygous state in an individual with autoimmunity/lymphoproliferation and severe hypogammaglobulinemia, however this variant was also detected in the heterozygous state in this individual's unaffected mother and sibling. This patient also harbored a heterozygous variant in the CASP9 gene (Clemente et al., 2015); Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss-of-function is a known mechanism of disease; This variant is associated with the following publications: (PMID: 31589614, 28249164, 33859323, 25569260, 27123465) -

The TNFRSF13B c.431C>G; p.Ser144Ter variant (rs104894650) is reported in the literature in the compound heterozygous state in individuals affected with primary antibody deficiency syndromes (Brignier 2015, Pulvirenti 2016), and reported in the heterozygous state in unaffected relatives (Clemente 2015). This variant is reported as pathogenic in ClinVar (Variation ID: 265340), and is found in the general population with an overall allele frequency of 0.0056% (14/251478 alleles) in the Genome Aggregation Database. This variant induces an early termination codon and is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Additionally, another nonsense variant at this nucleotide (c.431C>A; p.Ser144Ter) has been reported in the homozygous state in two siblings with common variable immunodeficiency (Salzer 2005). Functional studies of cells from these patients demonstrate a lack of mRNA and protein expression leading to severe B cell defects (Romberg 2013, Salzer 2005). Based on available information, this variant is considered to be pathogenic. References: Brignier AC et al. Early-onset hypogammaglobulinemia: A survey of 44 patients.
