    Study Notes

    Chediak-Higashi Syndrome

    • Rare, inherited disorder affecting neutrophilic granules.
    • Caused by a defect in the LYST gene, impacting lysosomal trafficking.
    • Characterized by abnormally large, purple-gray granules in neutrophils and other cells.
    • Impaired white blood cell chemotaxis and reduced bactericidal activity.
    • Hepatosplenomegaly (enlarged liver and spleen) and potential liver failure can occur.
    • Patients often exhibit albinism (lack of melanin) and photophobia (light sensitivity).
