NM_012452.3:c.17G>A
Variant summary
Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP4_StrongBS1_Supporting
The NM_012452.3(TNFRSF13B):c.17G>A(p.Arg6Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000052 in 1,613,944 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R6W) has been classified as Uncertain significance.

Immunodeficiency, common variable, 2    Uncertain:1 
This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 6 of the TNFRSF13B protein (p.Arg6Gln). This variant is present in population databases (rs747078163, gnomAD 0.05%). 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: 538713). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Not Available"; 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. -
