Abstract
Introduction
In most countries, hereditary tyrosinemia type 1 is not included in routine newborn screening.
Discussion
We present the case of a female newborn with prenatal diagnosis of hereditary tyrosinemia type 1 and clear identification of this disorder by succinylacetone measurement in cord blood and peripheral blood immediately after birth. Succinylacetone was 44 μmol/L (norm <5 μmol/L) and increased within 12 h to 87.5 μmol/L.
Conclusion
With the high toxic potential of downstream metabolites, these data clearly point out the necessity of early nitisinone treatment to prevent symptomatic disease.
