Transaldolase (TALDO) deficiency is a recently described inborn error of metabolism of the pentose phosphate pathway that so far has been diagnosed in only eight patients. In this article, we report the clinical course and biochemical findings of two newly identified patients with TALDO deficiency-two sons of consanguineous parents from Polish origin, presenting with neonatal onset of bleeding diathesis, haemolytic anemia, thrombocytopenia and hepatosplenomegaly. Subsequently the patients had persistent thrombocytopenia, a bleeding tendency, impaired liver function and fibrosis. Their physical and psychomotor development progressed normally.
