Clarification of Answer by bobbie7-ga on 11 Mar 2005 18:31 PST Dear Praxiteles, This is what I uncovered for now; however I will keep on searching. According to the The Federal Ministry for Education and Research (BMBF)Germany, of the approx. 30,000 known diseases, over 7,000 number among the rare diseases. According to the definition used in Europe, a disease is rare if less than 2,000 people suffer from it.
