Families are suffering from these diseases, by profound congenital bilateral deafness, progressive often silently and tragically – they do not talk about it – vision abnormalities, and balance problems due to inner that is why you do not know about them! 6 7 WHY IS THIS TESTING OPTIONAL? If these diseases are affecting our communities, why is testing optional? The new panel contains seven additional diseases that are less common, but they do exist in our community and the families affected are suffering terribly. While each individual and family need to decide if they want to take advantage of the new testing panel, it is advisable and recommended that people be screened, to ensure that their future family will not be affected. What Determines IF A Disease WILL BE ON THE DY PANEL? What are the criteria for choosing which genetic diseases should be tested? Dor Yeshorim only selects tests for genetic diseases that are recessive, frequently occurring in the Jewish commu- nity, devastating and/or fatal. In addition, tests added to the Dor Yeshorim testing panel must be reliable. Not WHAT IF OTHER GENETIC DISEASES APPEARED IN YOUR FAMILY ח״ו every test presently on the market meets these criteria.

Reaching out for assistance will help assure that healthy siblings can safely marry without fear of reoccurrence of the disease. All information will be held strictly confidential. Protecting your family’s emotional health is of utmost importance to us, just as it is our goal to protect your family from being affected by devastating genetic diseases. We presently have the ability to screen for additional ge- netic diseases that are not currently part of DY’s regular panel and the new optional panel. For example: • Various forms of genetically caused deafness. • Various forms of genetically caused blindness. • Usher Syndrome Type 3 And more. 8 9 WILL ADDITIONAL TESTS BE DOR YESHORIM, ADDED IN THE FUTURE? What is the goal of Dor Yeshorim? THE PAST, As tests for other fatal and/or debilitating diseases become available, they are reviewed by DY’s medical and rabbinical advisory boards. Decisions are based THE PRESENT upon the severity of symptoms, test reliability, carrier frequency and available therapies for the disease.
