Perforin Gene Analaysis in an Iranian Family with Familial Hemophagocytic Lymphohistiocytosis
Perforin gene (PRF1) mutations have been reported in 20-30% of patients with familial hemophagocytic lymphohistiocytosis (FHL), an immune disorder of infancy and early childhood. Cytotoxic T and natural killer (NK) cell activities are remarkably reduced or ab-sent in FHL patients. We report the first cases of familial hemophagocytic lymphohistiocy-tosis in an Iranian family with two siblings. E...
متن کاملPerforin gene mutations in adult-onset hemophagocytic lymphohistiocytosis.
Perforin gene (PRF1) mutations cause the primary form of hemophagocytic lymphohistiocytosis (HLH). We report a genetic defect of PRF1 in a 62-year-old Japanese man with recurrent episodes of HLH. Sequencing of PRF1 from both peripheral blood mononuclear cells and nail clippings showed compound heterozygous mutation, including deletion of two base pairs at codons 1090 and 1091 (1090-1091delCT) a...
متن کاملFamilial Hemophagocytic Lymphohistiocytosis with A665G Perforin Gene Mutation: A Case Report
Familial hemophagocytic lymphohistiocytosis (FHL) is a genetically heterogeneous disease. Presentation of the disease such as primarily fever, hepatosplenomegaly, and cytopenia, which are the results of functional degradation in cytotoxic T-lymphocytes and natural killer cells, activation of macrophages and T-lymphocytes, over production of proinflammatory cytokines, and hemophagocytosis. In al...
متن کاملPerforin expression in cytotoxic lymphocytes from patients with hemophagocytic lymphohistiocytosis and their family members.
Mutations in the perforin gene have been described in some patients with hemophagocytic lymphohistiocytosis (HLH), but the role of perforin defects in the pathogenesis of HLH remains unclear. Four-color flow cytometric analysis was used to establish normal patterns of perforin expression for control subjects of all ages, and patterns of perforin staining in cytotoxic lymphocytes (natural killer...
