Huntington Disease Burden of Pathology Calculator

Calculates the Huntington disease burden of pathology using CAG repeat length and age, estimating when symptoms will likely onset and disease progression stage using the unified Huntington disease rating scale components.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculates the Huntington disease burden of pathology using CAG repeat length and age, estimating when symptoms will likely onset and disease progression stage using the unified Huntington disease rating scale components

Each component has a specific meaning:

  • CAG repeat length — The cag repeat length recorded for the scenario being assessed.
  • Age — The age recorded for the scenario being assessed.
  • Estimating when symptoms will likely onset — The estimating when symptoms will likely onset recorded for the scenario being assessed.
  • Disease progression stage — The disease progression stage recorded for the scenario being assessed.

Note: Interpret the hd burden score result against the thresholds and context described above.

How to Use

Enter the CAG repeat length, age, estimating when symptoms will likely onset, disease progression stage for the scenario you are assessing. Calculates the Huntington disease burden of pathology using CAG repeat length and age, estimating when symptoms will likely onset and disease progression stage using the unified Huntington disease rating scale components. Use the hd burden score result to inform your calculation.
