Wiskott Aldrich syndrome (WAS) is a disease with immunological deficiency and reduced ability to form blood clots. Signs and symptoms include easy bruising. Wiskott Aldrich syndrome (WAS) is inherited in an X-linked recessive manner. A condition is X-linked if the responsible gene is located on the X chromosome. My husband’s grandmother had three children. Two of her sons with Wiskott Aldrich syndrome (WAS) died at ages 7 and 3. My husband’s father did not have it.

Ina German research group analysed family members of Wiskott’s three cases, and surmised they probably shared a novel frameshift mutation of the first exon of the WASp gene.

Due to combined immunodeficiency, enfermedaad patients also have airway, gut or skin infections caused by regular or opportunistic germs. In most cases the first clinical features are hemorrhagic manifestations with petechiae, bruising, purpura, epistaxis, oral bleeding, bloody diarrhea and intracranial bleeding.

Tauopathy Cavernous venous malformation. Enlargement of the spleen is not uncommon. WAS occurs most often in males due to its X-linked recessive pattern of inheritance, affecting between 1 and 10 males per million. InfancyNeonatal ICD Clinical description WAS usually manifests in infancy but onset may also occur during the neonatal period.

Usually, hypomorphic mutations in the WAS gene can lead to an attenuated form of WAS called X-linked thrombocytopenia with normal platelets XLTT; see this termthat is characterized by mild to moderate thrombocytopenia and eczema and a lower risk of autoimmunity and malignancy, but usually showing no immunodeficiency. Diagnosis is based on family history, physical examination and laboratory investigations that reveal severe thrombocytopenia with reduced platelet size with a usually normal number of megakaryocytes, as well as altered antibody production mainly antipolysaccharidic antibodies.

WAS patients have increased susceptibility to infections, particularly of the ears and sinuses, and this immune deficiency has been linked to decreased antibody production and the inability of immune T cells to effectively combat infection.
