SAP and XIAP [Interpretation] in Leukocytes by Flow cytometry (FC)
Active
Term Description
Analysis of SLAM (signaling lymphocytic activation molecule)-associated protein (SAP) and X-linked inhibitor of apoptosis protein (XIAP) levels by flow cytometry is performed as a preliminary screen for X-linked lymphoproliferative (XLP) disease and X-linked familial hemophagocytic lymphohistiocytosis (HLH). If SAP protein levels are absent or decreased, XLP is suspected. If XIAP protein levels are absent or decreased, HLH (aka XLP-2) is suspected. The diagnosis is confirmed by genetic analysis of the associated genes (SH2D1A gene for XLP, BIRC4 gene for HLH).
Part Description
LP212185-5 Signaling lymphocytic activation molecule (SLAM)-associated & X-linked inhibitor of apoptosis protein
Signaling lymphocytic activation molecule (SLAM)-associated protein (SAP) and X-linked inhibitor of apoptosis protein (XIAP) levels are measured for the diagnosis of X-linked lymphoproliferative (XLP) disease and X-linked familial hemophagocytic lymphohistiocytosis (HLH). XLP (aka XLP-1, Duncan disease, and Purtilo syndrome) and HLH (aka XLP-2) are two types of X-linked lymphoproliferative diseases described to date. XLP is caused by mutations in the SH2D1A gene, which encodes the cytoplasmic adaptor protein SAP. If the SAP protein is low, patients develop dysgammaglobulinemia, fulminant mononucleosis following infection with Epstein Barr virus (EBV), and B-cell lymphoma. HLH is caused by mutations in the XIAP gene, which encodes the XIAP protein. Patients with HLH commonly present with splenomegaly and recurrent episodes of hemophagocytic lymphohistiocytosis, often in response to EBV infection.[Atlas Genetics KPrones: XlinkedlymphoproliferID10028]
