TYR-I

Tyrosinemia type I is caused by fumarylacetoacetate hydrolase deficiency and can lead to liver failure, renal Fanconi syndrome, and neurologic crises if untreated. Nitisinone combined with dietary tyrosine and phenylalanine restriction has transformed prognosis when started early. Newborn screening identifies infants for treatment before hepatocellular damage advances.
