Familial hemophagocytic lymphohistiocytosis 3

Secretion of the contents of cytolytic granules at the immunologic synapse is a highly regulated process essential for lymphocyte cytotoxicity. This process requires the rapid transfer of perforin (170280)-containing lytic granules to the target cell interface, followed by their docking and fusion with the plasma membrane. Familial hemophagocytic lymphohistiocytosis is a genetically heterogeneous condition characterized by defective cytotoxicity. For a more detailed description of FHL, see 267700.
