Description : Autoimmune lymphoproliferative syndrome is a heritable disorder of apoptosis, resulting
in the accumulation of autoreactive lymphocytes. It manifests in early childhood as
nonmalignant lymphadenopathy with hepatosplenomegaly and autoimmune cytopenias (summary
by Dowdell et al., 2010). For a review of the autoimmune lymphoproliferative syndromes,
see Teachey et al. (2009). - Genetic Heterogeneity of Autoimmune Lymphoproliferative
Syndrome Type IIA ALPS (ALPS2A; 603909) is caused by mutation in the caspase-10 gene
(CASP10; 601762). Puck and Straus (2004) designated caspase-8 deficiency (607271),
caused by mutations in the CASP8 gene (601763), as type IIB ALPS. They stated that
type III ALPS comprises cases in which a mutation has not been identified. Type IV
ALPS (614470) is caused by mutation in the NRAS gene (164790).;
Inheritance : Autosomal dominant;
Molecular basis : Caused by mutation in the Fas ligand gene (FASL, 134638.0001); Caused by mutation in the Fas antigen gene (FAS, 134637.0001);
Neoplasia : Increased risk of malignant lymphoma;
Laboratory abnormalities : Increased levels of IgA; Increased levels of IgG; Elevated levels of vitamin B12; Direct Coombs positive; Platelet antibody positive; Neutrophil antibody positive; Phospholipid antibody positive; Smooth muscle antibody positive; Rheumatoid factor positive; Antinuclear antibody positive; Increased interleukin 10; Increased levels of IgM;
