Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Jul 18, 2017 | The C193R variant in the TNFRSF13B gene has been reported previously in an individual with features of both autoimmune lymphoproliferative syndrome and CVID; however, this individual also harbored a variant in the CASP9 gene that may also have contributed to the phenotype (Clemente et al., 2015). Additionally, this individual harbored a nonsense variant on the same TNFRSF13B allele (in cis). The C193R variant is observed in 6/66,548 (0.009%) alleles from individuals of non-Finnish European background in the ExAC dataset (Lek et al., 2016). The C193R variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. However, this substitution occurs at a position that is not conserved, and in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. We interpret C193R as a variant of uncertain significance. - |

Immunodeficiency, common variable, 2 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 12, 2024 | This sequence change replaces cysteine, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 193 of the TNFRSF13B protein (p.Cys193Arg). This variant is present in population databases (rs764125338, gnomAD 0.01%). This missense change has been observed in individual(s) with autoimmune lymphoproliferative syndrome and/or common variable immunodeficiency (PMID: 25569260, 33859323). ClinVar contains an entry for this variant (Variation ID: 449227). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt TNFRSF13B protein function with a negative predictive value of 80%. 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. - |
