2011年2月3日 · XLP type 1 (XLP-1) is caused by mutations in the gene SH2D1A (also named SAP), whereas mutations in the gene XIAP underlie XLP type 2 (XLP-2). Here, a comparison of the clinical phenotypes associated with XLP-1 and XLP-2 was performed in cohorts of 33 and 30 patients, respectively.
SAP and XIAP deficiency in hemophagocytic lymphohistiocytosis
Among primary HLH-related genes, SH2D1A and XIAP are genetically responsible for X-linked lymphoproliferative syndrome (XLP) due to signaling-lymphocytic-activation-molecule-associated protein (SAP) and XIAP deficiencies, respectively. XLP is characterized by extreme vulnerability to Epstein-Barr virus infection.

x-连锁淋巴组织细胞异常增生症(xlp)是一种少见、致死性强的原发性免疫缺陷病。xlp在男性人群中的发病率约为(2~3)/10 6 。xlp可以被分为2型:sh2d1a基因突变所致的xlp-1型和xiap基因突变所致的xlp-2型。xlp临床表现多样,常由eb病毒(ebv)感染所诱发。
Using Flow Cytometry to Screen Patients for X-linked ...
Flow cytometry can be used to measure lymphocyte SAP or XIAP protein expression, and can also be used to observe lymphocyte phenotypes and functional defects that are unique to XLP. This review will give a brief overview of the clinical manifestations and molecular basis of SAP deficiency and XIAP deficiency, and will focus on the use of flow ...
X-linked lymphoproliferative disease due to SAP/SH2D1A …
2011年1月1日 · X-linked lymphoproliferative disease (XLP1) is a rare immunodeficiency characterized by severe immune dysregulation and caused by mutations in the SH2D1A/ SAP gene. Clinical manifestations are varied and include hemophagocytic lymphohistiocytosis (HLH), lymphoma and dysgammaglobulinemia, often triggered by Epstein-Barr virus infection.

1998年10月1日 · We now show that a T-cell-specific, SLAM-associated protein (SAP), which contains an SH2 domain and a short tail, acts as an inhibitor by blocking recruitment of the...
SLAM receptors and SAP influence lymphocyte interactions
Mutations that affect the adaptor molecule SLAM-associated protein (SAP) lead to the genetic disorder X-linked lymphoproliferative syndrome (XLP), which is characterized by severe, often...
XLP: clinical features and molecular etiology due to mutations in ...
XLP is caused by loss-of function mutations in SH2D1A, which encodes the intracellular adaptor molecule SAP. SAP is predominantly expressed in T cells and NK cells, and functions to regulate signal transduction pathways downstream of the SLAM family of surface receptors to control CD4+ T cell (and by extension B cells), CD8+ T cell and NK cell ...
