We report, for the first time, a non-syndromic infant with a reversible myeloproliferative disease that harbors a germline hereditary thrombopoietin (THPO) gene mutation, a condition that is known to induce familial thrombocytosis at increasing age. In order to investigate whether somatic THPO gene mutations play a role in sporadic pediatric myeloproliferative diseases, we performed a mutation screening of a large representative cohort of pediatric acute myeloid leukemia, myeloid leukemia of Down syndrome, and juvenile myelomonocytic leukemia samples and show that gain-of-function THPO mutations are extremely rare in sporadic pediatric myeloproliferative diseases.
