Deficiency of fumarylacetoacetase in a patient with hereditary tyrosinemia. 1981

R Berger, and G P Smit, and S A Stoker-de Vries, and M Duran, and D Ketting, and S K Wadman

A patient is described with type I tyrosinemia characterized by urinary excretion of succinylacetone together with increased excretion of tyrosine, p-hydroxyphenyllactic, p-hydroxyphenylpyruvic and p-hydroxyphenylacetic acids. Fumarylacetoacetase was measured in a liver biopsy and found to be very low compared to control liver. Furthermore the mass spectra of succinylacetone and fumarylacetoacetate (methoxime-TMS derivatives) are reported. Control jejunal mucosa, leucocytes and fibroblasts showed no enzyme activity; hence the prenatal diagnosis of this disease by measuring the fumarylacetoacetase activity in cultured amniotic fluid cells is not possible at present.
