WebPatients usually have an expansion of more than 60 CAG repeats in the Huntington disease (HD) gene, and the disease is usually inherited from the father. In general, precise age at onset is difficult to assess in HD because of insidious onset and anosognosia. Onset of motor difficulty signs is usually used to define age at onset. Objectives: WebOct 1, 2024 · The results of diagnostic testing revealed a normal allele with 17 CAG repeats and expanded as well as an unstable polyglutamine-encoding allele with 52 CAG repeats. Because both positive genetic testing results and motor symptoms of the disease were present, the patient was diagnosed with JHD.
