    Abstract:
    Autoimmune lymphoproliferative syndrome (ALPS) usually manifests in early childhood with splenomegaly, lymphadenopathy, and cytopenias. In most patients, it results from mutations in genes that regulate lymphocyte apoptosis via the Fas pathway. Here, we report five children with ALPS. All five children had splenomegaly, cytopenias, and hypertriglyceridemia at presentation; four had lymphadenopathy. Mutations in the Fas receptor gene were demonstrated in three children. Clinical picture is variable: in only one child manifestations are severe enough to require immunosuppressive therapy. Diagnosis of ALPS can be challenging and increased awareness of the disease can result in more directed diagnostic approaches as well as earlier initiation of treatment.
