Canavan Disease Developmental Severity Assessment

Evaluates Canavan disease (aspartoacylase deficiency) severity using urine N-acetylaspartate levels, developmental milestone assessment, MRI white matter signal score, and macrocephaly percentile.

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

Evaluates Canavan disease (aspartoacylase deficiency) severity using urine N-acetylaspartate levels, developmental milestone assessment, MRI white matter signal score, and macrocephaly percentile

Each component has a specific meaning:

  • Urine N-acetylaspartate levels — The urine n-acetylaspartate levels recorded for the scenario being assessed.
  • Macrocephaly percentile — The macrocephaly percentile recorded for the scenario being assessed.

Note: Interpret the canavan severity result against the thresholds and context described above.

How to Use

Enter the urine N-acetylaspartate levels, macrocephaly percentile for the scenario you are assessing. Evaluates Canavan disease (aspartoacylase deficiency) severity using urine N-acetylaspartate levels, developmental milestone assessment, MRI white matter signal score, and macrocephaly percentile. Use the canavan severity result to inform your calculation.
