Screening for the Tay-Sachs carrier: a compromise program.

Abstract

A modified program designed to screen for the Tay-Sachs carrier is presented in which testing is limited to one or both partners, as needed, in an Ashkenazi Jewish (Jews of central and eastern Europe ancestry) mating when there is a definite commitment toward having a child, or in the early stages of the pregnancy. Testing of unmarried individuals is discouraged. The approach maximizes individualization of both the medical and laboratory aspects of the program and promotes a positive and beneficial relationship between physician and clinical chemist. There is little involvement of the lay population or clergy, and no special sources of funding are required. Whereas most mass screening programs for the Tay-Sachs carrier have attempted to educate large numbers of the lay public to bring pressure upon the medical community, we have reversed this approach and taken the much easier course of educating small numbers of physicians to better care for their patients. The program has been used successfully in a moderate-size city in which communication lines between laboratory and physician are easily established.
