The graph shows the age at onset (white bars) and the age at diagnosis (gray bars) of HHH syndrome patients. Patients are divided into four age categories: neonatal (birth —1 month) infantile (> 1 month—1 year), childhood (> 1 years— 12 yrs), and adolescence/adulthood (> 12 years). Values are expressed as percentage of the total.
