We report a CD40 ligand deficiency (CD40LD) patient who was successfully treated with unrelated cord blood transplantation (URCBT). Conditioning regimen was busulfan and cyclophosphamide. The clinical course was uneventful and durable engraftment was achieved. This successful case encourages the use of URCB as an alternative donor source for CD40LD patients.
Key words: CD40 ligand deficiency, X-linked hyper-IgM syndrome, unrelated cord blood transplantation, class-switched memory B cell, TREC.
