Wiskott-Aldrich Syndrome
Wiskott–Aldrich syndrome (WAS) is a rare X-linked primary immunodeficiency disorder characterized by the triad of eczema, microthrombocytopenia, and severe and often recurrent infections caused by mutation of WASp gene.[1]
- WASp is involved in actin polymerization and associated coupling of receptor engagement, signaling events, and cytoskeletal rearrangement[2]
Allogeneic stem cell transplantation is the only curative treatment for Wiskott-Aldrich syndrome[3]===X-LINKED THROMBOCYTOPENIA===
*X-linked thrombocytopenia (XLT), sometimes associated with mild eczema and/or infections, was recognized in the 1960s and was suspected to be a variant of WAS.patients with XLT shown to have mutations in the Wiskott-Aldrich syndrome protein gene (WAS).
X-linked thrombocytopenia (XLT) should be suspected in a male with:
- Congenital thrombocytopenia (5,000-50,000 platelets/mm3)
- Small platelet size (platelet volume <7.5 fL)
- Absence of other clinical findings of Wiskott-Aldrich syndrome
- Family history of one or more maternally related males with a WAS-related phenotype or disorder
- Decreased or absent WASP by flow cytometry or western blotting
- Some affected individuals have near-normal amounts of WAS
