ALPS-SFAS
- Heritable disorder of apoptosis, resulting in the accumulation of autoreactive lymphocytes.[1]
- Manifests in early childhood as nonmalignant lymphadenopathy with hepatosplenomegaly and autoimmune cytopenias.[1]
- Patients with mutations have developed B and T-cell lymphomas.[2]
- Peripheral blood analysis in patients has demonstrated hypergammaglobulinemia along with increased numbers of B and T lymphocytes.[3]
- Some studies have demonstrated that ALPS is compatible with long-term survival.[4][5]
Types of mutation
- Type IA is caused by heterozygous mutation in the FAS gene (TNFRSF6, or CD95)
- Type Ib is caused by heterozygous mutation in the FAS ligand (FASL) gene (TNFSF6 or CD95L)
RALD(RAS-associated autoimmune leukoproliferative disease)
- Originally considered a subtype of RAS due to the significant overlap.[6][7]
- A leukoproliferative disorder characterized by lymphadenopathy, splenomegaly, and variable autoimmune phenomena, including autoimmune hemolytic anemia, idiopathic thrombocytopenic purpura, and neutropenia.[6][7]
- Some patients have recurrent infections with increased risk of hematologic malignancy.[6][7]
