Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

CTLA4 and LRBA deficiencies are rare genetic disorders, recently described, and associated with multiple clinical features. It ranges from recurrent infections, auto-immunity, and organ infiltration with lymphocytes. Neurologic syndroms are described in up to 30% of patients, yet they are poorly defined to date. Early recognition of a specific pattern can be important, given that there is a targeted therapy in this situation.
