Profile of platelet count in males with intermittent thrombocytopenia and WASP gene mutations.

Profile of platelet count in patient 1 (closed circle), patient 2 (open circle), and patient 4 (open triangle) since they were first seen at the Department of Pediatrics, University of Brescia. The shaded area represents the normal range for platelet count. Only recent data were available for patient 3 (not shown), who had thrombocytopenia and a small mean platelet volume.
