TNFRSF13B (O14836) variants and mutations

TNFRSF13B (also known as O14836) is a human protein-coding gene encoding a tumor necrosis factor receptor superfamily member 13B protein. It responds to BAFF and APRIL and regulates B-cell survival, antibody production, and immunoglobulin class switching. Pathogenic variants are enriched in common variable immunodeficiency and can contribute to antibody deficiency, although penetrance is incomplete for many heterozygous alleles. This analysis covers 699 TNFRSF13B variants and mutations. Of these, 85% have computational variant effect predictions. Disease context includes immunodeficiency, common variable, 2, immunoglobulin A deficiency 2, and common variable immunodeficiency. Example TNFRSF13B variants include M1I, S2G, and S2N.
