tyrosinosis
A condition attributed to faulty tyrosine metabolism, in which parahydroxyphenyl pyruvic acid, an intermediate product, appears in the urine.The only patient with this condition was reported by G Medes in 1932. Because of the uncertainly whether Medes’s patient had a disease a sui generis, tyrosinosis has become a synonym for tyrosinemia type I, MIM 276700; given its nonspecificity, tyrosinosis may also be applied to both tyrosinemia type II (Richner-Hanhart syndrome), MIM 276600, and tyrosinemia type III, MIM 276710.
