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 was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.02599901).
BS1
Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000158 (24/152156) while in subpopulation AMR AF = 0.000851 (13/15270). AF 95% confidence interval is 0.000503. There are 1 homozygotes in GnomAd4. There are 11 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

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. -

Center for Genomics, Ann and Robert H. Lurie Children's Hospital of Chicago
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

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. -
