DETECTION OF TRINUCLEOTIDE REPEATS BY IN SITU HYBRIDIZATION

摘要

Disclosed is a method of detecting a trinucleotide repeat expansion by in situ hybridization. The disclosed method uses a sample of nucleated cells, a labelled trinucleotide repeat-specific probe and detection of the hybridized probe by a means whose sensitivity distinguishes between the signal from probes hybridized to an expanded repeat and the signal from probes hybridized to a non-expanded repeat.
