Question

Huntington disease (HD) can arise from a rare, short, in-frame addition of CAG nucleotide triplets within the huntingtin (HTT) gene coding region, which creates a disease-causing allele with the symptoms only appearing later in life. Using this information, describe an experiment that could be undertaken to determine whether a currently healthy young individual is a carrier of the HD-causing mutation. Describe the method you would use and how you would interpret the results of this experiment.
