Fig. 3: Age dependency of initial symptoms.
From: Insights into the expanding phenotypic spectrum of inherited disorders of biogenic amines
Age-dependent onset of initial symptoms in primary disorders of biogenic amine metabolism (a) and BH deficiencies (b). Initial symptoms reported in minimum 5 patients––except in arGTPCHD, DHPRD and SRD in minimum 3 patients. The percentages correlate with available data about both occurrence of the symptom and age at onset of disease and not to the whole disease group.
