A patient with impaired judgment, personality changes, signs of abnormal body movements and
depression comes to the physician's office for a follow-up visit. The physician suspects a single-gene

clinical laboratory for mutation screening in the Huntington gene. Testing with standard PCR indicates
that patient has Huntington Disease, HD. Which of the following would be consistent with this
diagnosis?
, 25 CAG repeats in the Huntington gene

25 CGA repeats in the Huntington gene
85 CGA repeats in the Huntington gene -
Answer☑️
85 CAG repeats in the Huntington gene
