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]

Submissions by phenotype

Immunodeficiency, common variable, 2 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpFeb 12, 2022This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 190 of the TNFRSF13B protein (p.Gly190Arg). This variant is present in population databases (rs150101848, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with TNFRSF13B-related conditions. ClinVar contains an entry for this variant (Variation ID: 579029). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C15"). 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. -
TNFRSF13B-related disorder Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesNov 04, 2022The TNFRSF13B c.568G>A variant is predicted to result in the amino acid substitution p.Gly190Arg. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.025% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/17-16843703-C-T). An alternate missense change at the same amino acid has been reported as a variant of uncertain significance in a patient with selective IgA deficiency (Pulvirenti et al. 2016. PubMed ID: 27123465). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
