Transaldolase deficiency in a two-year-old boy with cirrhosis.

Transaldolase (TALDO) deficiency is a rare inborn error of the pentose phosphate pathway. We report the clinical presentation and laboratory findings of a new patient with TALDO deficiency. The two-year-old Arabic boy presented with neonatal onset of anemia and thrombocytopenia, tubulopathy, and rickets and was subsequently found to have cirrhosis and deafness. A comparison with other TALDO deficient patients is given.
