Twenty-five Turkish infants with Tay-Sachs disease (TSD) have been diagnosed in the past 8 years. All are from consanguineous, nonrelated families. The present study deals with the molecular basis of six Turkish TSD patients from five unrelated families in which the parents were first cousins. The five mutations identified in this study were INS-5 G-->A, R393X, R137X, 12-bp deletion in exon 10, and G454D. The first three were reported in earlier studies, two in Turkish TSD infants and one in a French TSD infant. (C) 1998 Academic Press.
