Wilson's disease
From The School of Biomedical Sciences Wiki
Wilson disease is an inheritable autosomal recessive disorder and is a result of mutations in the APT7B gene. The APT7B gene encodes a protein required to remove surplus copper from the body, mutations in this gene reduce the functionality of the transport protein resulting in harmful accumulation of copper in the body http://ghr.nlm.nih.gov/condition/wilson-disease.
