Selective impairment of platelet activation to collagen in the absence of GATA1.


Defects in the X-linked DNA-binding megakaryocyte transcription factor GATA1 cause thrombocytopenia and abnormal platelet function. However, detailed studies of GATA1 function in platelet activation are lacking. Here, we studied platelets from GATA1-deficient mice and from a male patient (S14) with a bleeding diathesis attributed to a single amino acid… (More)
