General

Disease Name
Copper Toxicosis, COMMD1 Type
Mutation
c.179-36.6kb_458+2.9kbdel39.8k
Mutation 2

Test Type
Genetic Disease/Disorder
Details
Wilson's disease, and Copper Toxicosis (COMMD1 type) are hereditary diseases in which failure of the liver to expel dietary copper leads to a build-up of this toxic metal causing illness and death. It should be noted that there can be other, non-hereditary causes of copper built-up. In addition, it is possible there are breed-specific forms of these diseases where the mutations responsible have not yet been identified.
Details 2
A disorder of copper metabolism, due to a deficiency of ceruloplasmin, which forms a complex with copper. The excess copper is deposited in the brain (causing mental retardation) or the liver (causing jaundice and cirrhosis).
