    X-linked lymphoproliferative syndrome

    X-linked lymphoproliferative syndrome is a rare genetic disorder that affects how the immune system responds to infections, particularly the Epstein-Barr virus. This condition primarily affects males and can lead to serious, life-threatening complications if left untreated.
