Presentation of the data of the Italian registry for oculocutaneous tyrosinaemia

Abstract

Conclusions Type II tyrosinaemia in Italy has no regional preponderance. Neuromotor retardation and/or microcephaly seem to be correlated with the higher values of tyrosine. Enzyme studies have been refused in all patients. Treatment with a low tyrosine diet has been successful when accepted: since in many patients the diagnosis was made rather late, it is not possible to evaluate the results of the diet for the prevention of neuromotor retardation.
