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]

Uncertain significance, criteria provided, single submitter	clinical testing	Baylor Genetics	Jan 17, 2018	This variant was determined to be of uncertain significance according to ACMG Guidelines, 2015 [PMID:25741868]. -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Sep 13, 2022	This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 198 of the TNFRSF13B protein (p.Arg198Cys). This variant is present in population databases (rs140781824, gnomAD 0.1%). 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: 322026). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt TNFRSF13B protein function. 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. -

The c.592C>T (p.R198C) alteration is located in exon 4 (coding exon 4) of the TNFRSF13B gene. This alteration results from a C to T substitution at nucleotide position 592, causing the arginine (R) at amino acid position 198 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This variant has not been reported in the literature but is present in the Genome Aggregation Database (Highest reported MAF: 0.15% [15/10348]; https://gnomad.broadinstitute.org/variant/17-16843679-G-A?dataset=gnomad_r2_1) and is present in ClinVar (Variation ID: 322026). Evolutionary conservation and computational predictive tools suggest that this variant may not impact the protein. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
