Abstract：
Congenital thrombocytopenias are a genetically and clinically heterogeneous group of platelet disorders that are characterized by thrombocytopenia since birth. Although very rare, these disorders are encountered in routine clinical practice. Since 2011, the application of next generation sequencing has identified more than 15 new genes, which, when mutated, can cause congenital thrombocytopenia. Currently, at least 35 different forms have been identified. Although thrombocytopenia is congenital, some forms present an elevated risk of developing additional complications. In MYH9 disorders, patients often develop nephritis, deafness, and cataract. In a subgroup of congenital thrombocytopenias, with defects in the TPO/MPL signaling pathways or transcription factors, enhanced or reduced hematopoietic cell proliferation properties often culminates in the development of hematological malignancy or bone marrow failure. Proper and early genetic diagnosis is essential for the treatment of congenital thrombocytopenia.
