Hematopoietic Cells in Carriers of Wiskott-Aldrich Syndrome

The Wiskott-Aldrich syndrome (WAS) is an X-linked (Xpll.22) recessive immunodeficiency syndrome characterized by susceptibility to opportunistic and pyogenic infections, thrombocytopenia, and eczema. Previous studies of obligate carriers of WAS documented that nonrandom inactivation of the X chromosome carrying the defective gene is observed in all peripheral blood cells. The existence of b...

can occur, the observed improvement cannot necessarily b)e attributed to the transfer factor. However, in two patients repeated remissions consistently followed transfer factor administration on repeated occasions. This included freedom from infections, regression of splenomegaly, and clearing of eczema. An unexpected finding was a decrease in bleeding in 3 of the 10 patients who had bleeding. ...

BACKGROUND Wiskott-Aldrich syndrome is a rare X-linked immunodeficiency disorder with a variable phenotype. CASE CHARACTERISTICS 3.5-year-old boy diagnosed with Wiskott-Aldrich syndrome. OBSERVATION Unusual and persistent thrombocytopenia with increased platelet volume (>10fL). He did not exhibit characteristic clinical and laboratory finding for the syndrome.

Wiskott-Aldrich Syndrome Protein (WASP) Syndrome Impair the Interaction of Mutations That Cause the Wiskott-Aldrich

Atypical Wiskott-Aldrich syndrome in a girl.

Wiskott-Aldrich syndrome (WAS) is a fully penetrant X-linked recessive disorder characterized by thrombocytopenia with small platelets, eczema, and defects of both T-cell and B-cell immunity. Obligate carriers of this disorder show no signs of the gene defect because in the cell lineages primarily affected by the disorder they demonstrate preferential use of the normal, nonmutant X as the activ...
