<prompt> True about wilson;s diseaseIncrease in urinary copper and increased serum ceruloplasmin and copperIncreased serum ceruloplasmin levels with increased urinary copperElevated hepatic copper level and increased serum ceruloplasmin levelsIncreased in urinary copper and decreased serum ceruloplasmin  <response>: Wilson disease is an inborn error of metabolism due to toxic accumulation of copper in liver,brain,cornea and other tissues.Serum ceruloplasmin is decreased20 mgdl and the 24 hour urinary copper excretion is more than 100 microgramsday.Hepatic copper values usually above 250 micrograms gram of dry weight of liver.
