  • 3. Kayser-Fleischer rings (KF rings) • Are dark rings that appear to encircle the iris of the eye. They are due to copper deposition as a result of particular liver diseases. • Kayser-Fleischer rings do not cause any symptoms.

  • 6. Classification • The Wilsons disease gene (ATP7B) has been mapped to chromosome 13 (13q14.3) and is expressed primarily in the liver, kidney, and placenta. • Mutations can be detected in 90%. Most (60%) are homozygous for ATP7B mutations (two abnormal copies), and 30% have only one abnormal copy. Ten per cent have no detectable mutation.
