Whole-genome and repertoire sequencing, bacteriophage immunizations, and deep immunophenotyping were used to compare affected and unaffected family members. The clinical phenotype of three affected siblings with hypomorphic RAG deficiency ranged from combined immunodeficiency and early mortality to a late-onset CID with hyper-IgM phenotype. T cells were remarkably similar across affected siblings, yet CDR3 skewing and regulatory T cell defects were not observed. B cell analysis showed elevated unswitched CD27+ and CD21<sup>low</sup> cells as well as features of an autoreactive antibody repertoire and presence of secreted autoantibodies, yet no clinical autoimmunity was present. Most striking was an expanded polyclonal marginal zone-like B cell population (IgM+IgD+CD27+) utilizing the self-reactive unmutated VH4-34 receptor demonstrating that hypomorphic RAG deficiency can promote expansion of self-reactive B cells. This process, however, was not sufficient to trigger clinical autoimmunity. Utilizing multiple approaches, we functionally measured the specific RAG2 variant effects and assessed how selection and secondary triggers altered the BCR repertoire and immunophenotype overtime.

The haematopoietic cell transplantation comorbidity index (HCT-CI) score predicts transplant survival in non-malignant diseases, including IEIs. We hypothesised that immune dysregulation pre-transplant may also influence transplant outcomes. We calculated the pre-transplant immune dysregulation and disease activity score (IDDA v2.1) for 82 adolescent and adult IEI patients (aged ≥ 13 years). Three-year overall survival (OS) for the whole cohort was 90% (n = 82) with a median follow up of 44.7 months (range 8.4 to 225.8). Events were defined as acute graft-versus-host disease (GvHD) grades II or above, chronic GvHD of any grade, graft failure, or death from any cause. Three-year event free survival (EFS) for the whole cohort was 72%. In multivariable analysis the IDDA v2.1 score pre-transplant and HCT-CI score significantly impacted OS (hazard ratio 1.08, p = 0.028) and EFS (hazard ratio 1.04, p = 0.0005). Importantly, 35% of this cohort had a high IDDA v2.1 score (≥ 15) and low HCT-CI score (< 3) suggesting that the risks of alloHSCT may be underestimated in a proportion of patients with IEI if the HCT-CI score is used alone. These findings support the potential for improved outcomes following successful modulation of immune dysregulation pre-transplant.
