JDP Congenital platelet disorders usually refer to inherited platelet disorders, which are transferred genetically. The strict definition of congenital is that the person is born with the disorder, however, so the term also applies to infants who are born with platelet disorders for other reasons. For example, neonatal thrombocytopenia is often caused by infection before birth. Another example is transient immune thrombocytopenic purpura, which can be transferred to the baby in rare cases if the mother has antibodies against platelets. Congenital platelet disorders that are acquired in utero are transient; the babies usually recover with treatment and do well.
