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.

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. Ornithine transcarbamylase deficiency Oculocerebrorenal syndrome Dyslipidemia: Alfred Wiskott —a German pediatrician who first noticed the syndrome in Studies of correcting Wiskott—Aldrich syndrome with gene therapy using a lentivirus have begun.
WAS usually manifests in infancy but onset may also occur during the neonatal period. Agonists of the thrombopoietin receptors such as romiplostim and eltrombopag can be used to increase the platelet count in severe refractory thrombocytopenia cases that are awaiting HSCT or gene therapy.

Keratinopathy keratosiskeratodermahyperkeratosis: Genetic counseling WAS is an X-linked recessive disease.
No geographical factor is present.
Diagnostic methods Diagnosis is based on family history, physical examination and laboratory investigations that reveal severe thrombocytopenia with reduced platelet size aldrlch a usually normal number of megakaryocytes, as well as altered antibody production mainly antipolysaccharidic antibodies. D ICD – As WAS is primarily a disorder of the blood-forming tissues, a hematopoietic stem cell transplant, accomplished through a umbilical cord blood or bone marrow transplant offers the only current hope of cure.
Due to combined immunodeficiency, most patients also have airway, gut or skin infections caused by regular or opportunistic germs. Long QT syndrome 4 Hereditary spherocytosis 1.

Often, leukemia may be suspected on the basis of low platelets and alddich, and bone marrow biopsy may be performed. Aspirin and other nonsteroidal anti-inflammatory drugs should be avoided, since these may interfere with platelet function which is already compromised.
