Variant summary

Our verdict is Likely benign. Variant got -4 ACMG points: 2P and 6B. PM2 BP6_Moderate BS1

The NM_001561.6(TNFRSF9):​c.680-3dupT variant causes a splice region, intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00214 in 1,499,784 control chromosomes in the GnomAD database, with no homozygous occurrence. 1/1 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Benign (★).

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 -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP6: Variant 1-7920925-T-TA is Benign according to our data. Variant chr1-7920925-T-TA is described in ClinVar as [Benign]. Clinvar id is 1165231.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.00235 (3172/1349392) while in subpopulation NFE AF= 0.00256 (2651/1034194). AF 95% confidence interval is 0.00248. There are 0 homozygotes in gnomad4_exome. There are 1532 alleles in male gnomad4_exome subpopulation. Median coverage is 28. This position pass quality control queck.
