Genes affected

TNFRSF9 (HGNC:11924): (TNF receptor superfamily member 9) The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptor contributes to the clonal expansion, survival, and development of T cells. It can also induce proliferation in peripheral monocytes, enhance T cell apoptosis induced by TCR/CD3 triggered activation, and regulate CD28 co-stimulation to promote Th1 cell responses. The expression of this receptor is induced by lymphocyte activation. TRAF adaptor proteins have been shown to bind to this receptor and transduce the signals leading to activation of NF-kappaB.

ACMG classification

Verdict is Likely_benign. Variant got -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.035987407).
• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0000526 (8/152086) while in subpopulation EAS AF= 0.00116 (6/5172). AF 95% confidence interval is 0.000505. There are 0 homozygotes in gnomad4. There are 6 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 244 of the TNFRSF9 protein (p.Arg244Gln). This variant is present in population databases (rs554909019, gnomAD 0.09%). This variant has not been reported in the literature in individuals affected with TNFRSF9-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glutamine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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. -
