Congenital amegakaryocytic thrombocytopenia (CAMT) is an autosomal recessive disorder characterized by thrombocytopenia with an absence of megakaryocytes. It can lead to aplastic anemia or myelodysplastic syndrome (MDS). CAMT is linked to a mutation in the c-MPL gene on chromosome 1, which encodes the thrombopoietin receptor. In 2005, CAMT was categorized into three types based on the severity of c-MPL gene loss. Type 1 is the most severe, leading to early-onset pancytopenia and bone marrow abnormalities. Type 2 shows a temporary increase in platelets during infancy, followed by bone marrow failure at 3-6 years due to partial gene function. Type 3 has normal c-MPL function but produces ineffective megakaryocytes. We report a case of a patient with CAMT-like symptoms, without a c-MPL gene mutation, suggesting the presence of an alternative genetic defect.
