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]

ACMG classification

Classification made for transcript

Verdict is Pathogenic. Variant got 14 ACMG points.

PVS1
Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. There are 7 pathogenic variants in the truncated region.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 17-16972026-TG-T is Pathogenic according to our data. Variant chr17-16972026-TG-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 538707.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Immunodeficiency, common variable, 2 Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMar 18, 2021For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in TNFRSF13B are known to be pathogenic (PMID: 16007087, 27123465). This variant has not been reported in the literature in individuals with TNFRSF13B-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Gln17Argfs*15) in the TNFRSF13B gene. It is expected to result in an absent or disrupted protein product. -

Likely pathogenic, criteria provided, single submitterclinical testingGeneDxJun 13, 2019The c.49delC variant in the TNFRSF13B gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The c.49delC variant causes a frameshift starting with codon Glutamine 17, changes this amino acid to an Arginine residue, and creates a premature Stop codon at position 15 of the new reading frame, denoted p.Gln17ArgfsX15. This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The c.49delC variant is not observed in large population cohorts (Lek et al., 2016). We interpret c.49delC as a likely pathogenic variant. -
