Low platelets refer to the decrease in the number of platelets in the peripheral blood, which is below the normal range. Generally, the diseases that commonly cause thrombocytopenia in clinical practice are not hereditary diseases, so low platelets are not inherited. The disease that commonly causes thrombocytopenia in the clinic is immune thrombocytopenic purpura, which is an autoimmune disease, due to the production of autoantibodies against platelets, resulting in excessive destruction of platelets in the peripheral blood, and also accompanied by impaired maturation of megakaryocytes, so this disease is an autoimmune disease, not a hereditary disease, it is not inherited. In addition, other common diseases that cause thrombocytopenia include aplastic anemia, myelodysplastic syndrome, and paroxysmal sleep hemoglobinuria, all of which are not hereditary diseases, so low platelets are not inherited. Moreover, the main cause of low platelets in clinical practice is autoimmune diseases.
