Abstract

Familial hemophagocytic lymphohistiocytosis (FHL) is a genetically heterogeneous hyperinflammatory syndrome, caused by an uncontrolled and ineffective proliferation and activation of T-lymphocytes, NK-cells, and macrophages that infiltrate multiple organs. Herein, a patient is presented who suffered from hepatitis and atypical brain lesions. Genetic studies revealed a homozygous mutation in the STXP2 gene; and thus, the diagnosis of FHL5 was confirmed. © 2014, Springer Science+Business Media New York.
