autoimmune lymphoproliferative syndrome type 3

Disease Summary
Associated Targets (1)


Mondo Description A rare, primary immunodeficiency. It is caused by a currently undetermined defect in the Fas-induced apoptosis pathway. No mutations in Fas, FASLG or CASP10 are detectable. Disruption of Fas-induced apoptosis impairs lymphocyte homeostasis and immune tolerance. Characteristic laboratory findings include an increase in circulating, double-negative (CD4-/CD8-) T cells in the setting of immune-mediated anemia, thrombocytopenia and neutropenia. Clinical signs present in childhood include fatigue, pallor, bruising, hepatosplenomegaly and chronic, non-malignant, non-infectious lymphadenopathy. The clinical course is influenced by a strong association with other autoimmune disorders and an increased risk for developing Hodgkin and non-Hodgkin lymphoma.
Uniprot Description A primary immunodeficiency characterized by antibody deficiency, hypogammaglobulinemia, recurrent bacterial infections and an inability to mount an antibody response to antigen. The defect results from a failure of B-cell differentiation and impaired secretion of immunoglobulins; the numbers of circulating B-cells is usually in the normal range, but can be low. CVID9 patients have B-cell deficiency and severe autoimmunity.
Disease Ontology Description An autoimmune lymphoproliferative syndrome that has material basis in homozygous mutation in the PRKCD gene on chromosome 3p21.
