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]

Pathogenic, no assertion criteria provided	clinical testing	Biochemical Molecular Genetic Laboratory, King Abdulaziz Medical City	Jun 07, 2020	- -
Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 10, 2024	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. -
