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.Cys193*) 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 (rs72553885, gnomAD 0.01%). This premature translational stop signal has been observed in individual(s) with TNFRSF13B-related conditions (PMID: 18981294, 27123465, 30993493). ClinVar contains an entry for this variant (Variation ID: 657318). For these reasons, this variant has been classified as Pathogenic. -

The TNFRSF13B c.579C>A; p.Cys193Ter variant (rs72553885, ClinVar Variation ID 657318) is reported in the literature in the heterozygous or compound heterozygous state in individuals affected with primary antibody deficiency syndromes or common variable immunodeficiency; phenotypes are variable and include asymptomatic heterozygous family members (Bisgin 2021, Fioredda 2022, Grossi 2021, Leonardi 2019, McLean-Tooke 2019, Pulvirenti 2016, Rojas-Restrepo 2021, Salzer 2009). This variant is found in the general population with an overall allele frequency of 0.0057% (16/281810) in the Genome Aggregation Database (v2.1.1). This variant induces an early termination codon and is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Based on available information, this variant is considered to be pathogenic. References: Bisgin A et al.
