tyrosinemia type ii is a rare autosomal recessive disorder wich can present itself with recurrent epithelial keratitis, hyperkeratotic skin lesions and mental retardation. this article reports the rare occurrence of this disease in both offsprings (two brothers) of a family (consanguinous'marriage) who were managed with a lowprotein diet and a special regimen.

background: tyrosinemia type 1 is an autosomal recessive metabolic disorder, which typically affects liver and kidneys. it is caused by a defect in fumarylacetoacetate hydrolase or fumarylacetoacetase (fah) enzyme, the final enzyme in the tyrosine degradation pathway. the disease typically manifests as early onset type in early infancy with acute hepatic crisis with hepatomegaly and bleeding te...

Richner-Hanhart syndrome (tyrosinemia type II) is a rare autosomal recessive disease associated with high serum tyrosine levels caused by the deficiency of tyrosine aminotransferase enzyme. We report a 15-year-old female patient with complaints of bilateral photophobia and tearing, which started during the infancy period. Biomicroscopic examination revealed bilateral circular corneal opacities ...

Progressive hepatocellular dysfunction in a neonate, resulting in elevated serum alpha-fetoprotein together with raised blood levels of tyrosine and methionine, a generalized amino aciduria and the absence of urinary delta-aminolevulinic acid and succinylacetone, suggests a diagnosis of tyrosinemia type Ib. Classical tyrosinemia type I arises from a deficiency of fumarylacetoacetate hydrolase w...

BACKGROUND Tyrosinemia type I is an autosomal recessively inherited metabolic disease of tyrosine metabolism due to the deficiency of fumarylacetoacetate hydrolase. Clinical manifestations include hepatic failure, cirrhosis, hepatocellular carcinoma, renal fanconi syndrome, and neurologic crisis. With the introduction of 2-(2-nitro-4-trifluoro-methylbenzyol)-1.3 cyclohexanedione (NTBC) treatmen...

Tyrosinemia type 1 is an inherited metabolic disorder attributable to deficiency of fumarylacetoacetate hydrolase enzyme. Here we report an eight month-old male Saudi infant who presented with jaundice, fever, and disturbed level of consciousness accompanied by abdominal distension, hepatomegaly and ascites with features suggestive of rickets. The diagnosis of tyrosinemia typ 1was confirmed bas...
