We’ve got identified a non-consanguineous family, who carry the C104R (c.310T4C) mutation in the Transmembrane Activator Calcium-modulator and cyclophilin ligand Interactor (TACI, TNFRSF13B) gene. Variants in TNFRSF13B/TACI are identified in as much as 10 of CVID sufferers, and are related with, but not solely causative of CVID. The proband is heterozygous for the TNFRSF13B/TACI C104R mutation and meets the Ameratunga et al.Fmoc-L-Ala(BCP)-OH In stock diagnostic criteria for CVID as well as the American College of Rheumatology criteria for systemic lupus erythematosus (SLE).PMID:36014399 Her son has type 1 diabetes, arthritis, lowered IgG levels and IgA deficiency, but has not inherited the TNFRSF13B/TACI mutation. Her brother, homozygous for the TNFRSF13B/TACI mutation, is in good overall health in spite of profound hypogammaglobulinemia and mild cytopenias. We hypothesised that a second unidentified mutation contributed towards the symptomatic phenotype in the proband and her son. Whole-exome sequencing with the family members revealed a de novo nonsense mutation (T168fsX191) inside the Transcription Element 3 (TCF3) gene encoding the E2A transcription aspects, present only inside the proband and her son. We demonstrate mutations of TNFRSF13B/TACI impair immunoglobulin isotype switching and antibody production predominantly by means of T-cell-independent signalling, although mutations of TCF3 impair each T-cell-dependent and -independent pathways of B-cell activation and differentiation. We conclude that epistatic interactions involving mutations from the TNFRSF13B/TACI and TCF3 signalling networks result in the serious CVID-like disorder and SLE inside the proband.
