I was diagnosed in 2003.  I have had a Bx and confirmation from the Mayo Clinic that there is accumilation of Iron in the Liver.  I never heard of HHC untill my P.C.P. had an idea to furtur test me because of high AST/ALT readings.  My father hasn't shown any evidence of  related illness.  My mother has Fibromyalgia and a niece has Hashimoto's.  Diabetes runs in my mother's side (boy! does it ever).  I have leared alot about the genetics and treatment of HHC.  National Institute of Health as an excellent treatment that takes out 2x the amount of red blood cells as opposed to a phelbotomy.  This process is called Aspheresis.  I have learned to deal with this and to realize the symptoms when they arise which means I may need to have another blood withdrawl.
