Clinical characteristics of the patients. AO = age of onset, TFC = Total functional capacity (UHDRS), IS = Independence score (UHDRS), CAG = CAG-ranges (low/high); Intensity: - = none, + = mild, ++ = moderate, +++ = severe. ND = no data. One patient (*) was treated twice with an increased dose of valproic acid within a 4 year period, see text.
