Since studies of the giant platelets in the Bernard-Soulier syndrome have shown decreased electrophoretic mobility, decreased sialic acid, and an abnormality in a membrane glycoprotein, we performed similar studies on the giant platelets from two patients with the May-Hegglin anomaly. The patients' platelet electrophoretic mobilities did not differ from control. Although the total sialic acid c...
