Without proper management of such complex biological and clinical data, artificial intelligence (AI) algorithms alone cannot be effectively trained, validated, and successfully applied to provide trustworthy and patient-centric diagnosis, prognosis and treatment.

The strongest association signals in most vasculitides correspond to genetic variants within the <em>HLA</em> region, suggesting an important role of the immune system in its pathophysiology. However, each type of vasculitis has distinct defining <em>HLA</em> association markers, likely due to disease-specific differences in antigenic drivers.
