genetics of Menke's disease
Last reviewed 01/2018
The gene involved in the pathogenesis of Menke's disease is found at chromosome Xq13.3.
The gene product (MNK) is a cation-binding P-type ATPase which is expressed in all tissues except the liver (1)
- there is mutation of ATP 7A gene (MNK; chromosome Xq13.3) which encodes a copper transporting enzyme adenosine triphosphatase responsible for intestinal absorption of copper (2)
