Biallelic discrimination assays for the three common Ashkenazi Jewish mutations and a common non-Jewish mutation, in Tay-Sachs disease, using fluorogenic TaqMan probes.

Abstract excerpt

We have developed rapid semiautomated fluorogenic TaqMan assays for the three common Jewish mutations that occur in Tay-Sachs disease, the TATC 4-bp insertion in exon 11 (1,278insTATC), the IVS 12 + 1G --> C, splice site mutation in intron 12 (1421 + 1 G --> C), and the G --> A change at the 3' end of exon 7 (G269S), as well as for a non-Jewish mutation, IVS9 + I G --> A, believed to be prevalent in patients of...
