You have been referred for a Genetic Consultation. Usually doctors refer a person for a Genetic Consultation because there is concern about a genetic cause for his/her illness or the illness affecting his/her child or family member that may or may not be “running in the family”. Because of that at Genetic Consultations information is gathered about you as well as your family members. So when you come for a Genetic Consultation it is necessary:
  • that you find out as much as possible about your own illness. 
  • that you find out as much as possible about illnesses in other members of your immediate and extended family including grandparents, aunts, uncles and their children.
  • to bring all relevant medical records not only of yourself but also of relavent relatives including previous x-rays, photos of diseased people or photos of a person before he/she developed the illness (if relevant only), etc.
