What are the causes of chronic moderate autoimmune neutropenia & moderate-severe thrombocytopenia with giant platelets? occasionally anemic.

Autoimmunity: The development of an autoimmune disease is most likely from impaired regulation of the immune function leading to immunologic attack on one's own tissue. The presence of one autoimmune disease increases the risk to develop another one probably from the impaired regulation. However we have still much to learn about autoimmunity as to why some people are more prone to it (female are more at risk).
