A growing number of patients presenting severe combined immunodeficiencies associated with Rac2 mutations have been identified in newborns. These mutations are associated with high frequency of infection, leukopenia and more rarely autoinflammatory features. Here, the inventors show that the Rac2 activating mutations activates the NLRP3 inflammasome leading to the secretion of IL-1β from macrophages depending on their activation strength. Therefore, inhibiting GasderminD (GSDMD) pathway should be considered as a potential treatment for these patients. The present invention relates to a method of treating Rac2 monogenic disorders in a subject in need thereof comprising the administration of an inhibitor of GasderminD (GSDMD).
