Inherited Thrombocytopenia with a Different Type of Gene Mutation: A Brief Literature Review and Two Case Studies

Hereditary thrombocytopenias are rare bleeding disorders, which cause a deficiency of platelets in early infancy. This group of dis- orders is sometimes associated with abnormal phenotypes, like absence of radius. Diagnosis of this type of thrombocytopenia is usually dicult; other causes of thrombocytopenia, such as immune disorders and infections, must be ruled out. The symptoms of hereditary thrombocytopenia also vary from seldom and mild to severe bleeding and occasionally may first occur in late childhood. In this group of patients, we must dierentiate heritable disorders from the acquired types of thrombocytopenia, like immune thrombocytopenic purpura. It is also important to watch for pitfalls to avoid unnecessary and potentially hazardous treatment. Herein, we briefly review the recent literature on hereditary thrombocytopenia and then present the cases of two referred patients. The first case had suered from persistent thrombocytopenia since early infancy and was diagnosed with congenital amegakary-
