Abstract excerpt
Total RNA was isolated from cultured fibroblasts from 12 unrelated patients with Tay-Sachs disease, an autosomal recessive disorder due to beta-hexosaminidase A deficiency. beta-Hexosaminidase mRNA was amplified by cDNA-PCR in four overlapping segments spanning the entire coding sequence. In two patients, abnormal size cDNA-PCR fragments in which exons were removed resulted from splicing mutations that were...
