Diagnostic copper imaging of Menkes disease by synchrotron radiation-generated X-ray fluorescence analysis.

Abstract excerpt

Copper (Cu) is an indispensable metal for normal development and function of humans, especially in central nervous system (CNS). However, its redox activity requires accurate Cu transport system. ATP7A, a main Cu(2+) transporting-ATPase, is necessary to efflux Cu across the plasma membrane and synthesize cuproenzymes. Menkes disease (MD) is caused by mutations in ATP7A gene. Clinically, MD is Cu deficiency...
