For example, macrothrombocytopenia associated with leukocyte inclusion, cataracts, nephropathy and/or deafness is often caused by mutations in the MYH9 gene [2,3] whilst the Gray Platelet Syndrome characterized by the presence of large and “pale” platelets is often caused by mutations in the NBEAL2 gene [13–15]. Here, MYH9 is linked to Macrothrombocytopenia.
