GPVI deficiency leads to a partial reduction in thrombin generation. Thrombin generation assay was performed in platelets from control, GP6^het, and GP6^hom patients. (A) Thrombin generation curves from a control, GP6^het, and GP6^hom individual are shown. (B) ETP is shown. (C) Peak height is shown. Data are resented as mean ± SD; control = 3, GP6^het = 2, and GP6^hom = 3.
