The S870N variant in the NFKB2 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The S870N variant was not observed in approximately 6200 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The S870N variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position that is conserved across species. In silico analysis predicts this variant is probably damaging to the protein structure/function. Missense variants in nearby residues (D865G, A867V) have been reported in the Human Gene Mutation Database in association with common variable immunodeficiency (Stenson et al., 2014), supporting the functional importance of this region of the protein. Therefore, we interpret S870N as a likely pathogenic variant
