Abstract excerpt
We have developed a sequence-specific internal DNA size standard for the accurate determination of the number of CAG repeats in the Huntington disease (HD) gene by cloning key fragments (between 15 and 64 CAG repeats) of the HD gene. These fragments, pooled to produce a sequence-specific DNA ladder, enabled us to observe the true number of CAG repeats directly, with no need for calculations. Comparison of the...
