Hi thanks for contacting healthcare magic. Noted you have fatty liver disease... Your DNA testing is positive, and you have skin discoloration and joint pain like symptoms ...So yes chances of hemochromatosis is high... PCR or FISH testing done for detecting HFE gene mutation ..That is present in congenital hemochromatosis... Here liver biopsy will be helpful to confirm hemochromatosis. In blood examination serum ferritin will be high... Acquired causes for hemochromatosis also has to be ruled out like hemolytic anemia. Meanwhile take low fat diet with more fruit to rest liver. Avoid alcohol if habit of it. Use less oil in cooking... After confirmation of hemochromatosis therapeutic phlebotomy or desferrioximine like drug can be done to treat it. Hope your concern solved.. Take care. Dr.Parth
