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]

Variant summary: TNFRSF13B c.563A>T (p.Lys188Met) results in a non-conservative amino acid change located in the intracellular domain (Fried 2011) of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0046 in 276498 control chromosomes in the gnomAD database, including 27 homozygotes. The observed variant frequency is approximately 1600 fold above the estimated maximal expected allele frequency for a pathogenic variant in TNFRSF13B causing Common Variable Immunodeficiency (CVID) phenotype (2.9e-06), strongly suggesting that the variant is benign. Though c.563A>T has been reported in the literature in individual(s) affected with sporadic CVID (Grimbacher 2006), this report does not provide unequivocal conclusions about association of the variant with CVID. At least one publication reports experimental evidence evaluating an impact on protein function. These results showed no damaging effect of this variant for protein expression, ligand binding and signaling function (Fried 2011). Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as benign/likely benign. Based on the evidence outlined above, the variant was classified as benign. -
