Variant summary
Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BP4_Strong
The NM_012452.3(TNFRSF13B):c.716C>T(p.Ala239Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000137 in 1,606,302 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. A239A) has been classified as Likely benign.

Immunodeficiency, common variable, 2 Uncertain:1
This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 239 of the TNFRSF13B protein (p.Ala239Val). This variant is present in population databases (rs375891337, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with TNFRSF13B-related conditions. ClinVar contains an entry for this variant (Variation ID: 471370). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
