MYH9 and Macrothrombocytopenia: Furthermore, in a potentially diagnostically relevant development, using MYH9 related macrothrombocytopenia as a model for an inherited human platelet cytoskeletal disorder, affecting platelet non-muscle myosin heavy chain IIa (NMMHC-IIA), we demonstrate that the choice of ex vivo anticoagulant may strongly impact the outcomes of mechanophenotyping.
