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	GeneDx	Dec 11, 2020	In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; In addition, in silico splice predictors suggest this variant may lead to abnormal gene splicing. In the absence of RNA/functional studies, the actual effect of this sequence change is unknown; Has not been previously published as pathogenic or benign to our knowledge -

This sequence change replaces proline with arginine at codon 97 of the TNFRSF13B protein (p.Pro97Arg). The proline residue is highly conserved and there is a moderate physicochemical difference between proline and arginine. This variant is present in population databases (rs754139414, ExAC 0.001%). This variant has not been reported in the literature in individuals affected with TNFRSF13B-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. -
