MYH9 disorders, whose prototype is May Hegglin Anomaly (MHA), are characterized by a triad of thrombocytopenia, giant platelets, and leukocyte inclusion bodies, to varying degrees, and are occasionally accompanied by nephritis, cataracts, and difficulty hearing [1–3]. MYH9 disorders are rare genetic disorders caused by abnormalities in the nonmuscle myosin heavy chain-9 (MYH9) gene located on chromosome 22q12-13 that encodes nonmuscle myosin heavy chain-IIA (NMMHC-IIA). The gene discussed is MYH9; the disease is macrothrombocytopenia and granulocyte inclusions with or without nephritis or sensorineural hearing loss.
