I met Randy Yudenfriend-Glaser recently at the convention for Reform Rabbis in New Orleans and she opened my eyes in a new way to the issue of testing for genetic diseases.
I had always thought that testing for the genetic diseases most common in Ashkenazi Jews was a waste of time for interfaith couples as clearly one partner wasn’t Jewish and couldn’t be a carrier. I have been corrected.
The nineteen devastating genetic diseases found most commonly in the Ashkenazi Jewish population are not only found in Jews. They are found in other ethnic groups as well, just less frequently. This means that even a non-Ashkenazi Jew, even a non-Jew, can be a carrier of one or more of these 19 very serious diseases.
The Jewish Genetic Disease Consortium strongly recommends that if only one grandparent of the couple was of Ashkenazi background, the simple blood test screening is necessary.
The protocol is: the member of the couple with the Ashkenazi background is screened first. If he or she is found to be a carrier, a genetic counselor will be able to recommend the proper screening for the spouse/partner. If both members of the couple are carriers of a mutated gene for the same genetic condition, there is a 25% chance – with each pregnancy – of having an affected child, a 50% chance that a child will be a carrier of the disease, and a 25% chance the child will be neither a carrier nor affected.
