The mutation causing juvenile Tay-Sachs disease (TSD) in two sibs of Lebanese-Maronite origin is described. An mRNA-containing extract of cultured fibroblasts obtained from one of the probands was used as a template to amplify the coding sequence of the hexoaminidase A (Hex A) a-subunit. Sequencing
Tay-Sachs disease is an autosomal recessive disorder affecting the central nervous system. The disorder results from mutations in the gene encoding the ~-subunit of Γ-hexosaminidase A, a lysosomal enzyme composed of ~ and Γ polypeptides. Seventy-eight mutations in the Hex A gene have been described
