Individual values for the ratio of plasma dihydroxyphenylalanine (DOPA): dihydroxyphenylglycol (DHPG) in familial dysautonomia patients upon initial evaluation and after an interval of 13 years. Horizontal bars indicate mean values. Gray zone indicates values within 2 standard deviations of the control mean value. Note that all familial dysautonomia patients had an initial DOPA:DHPG ratio more than 2 standard deviations above the control mean and that the patients had a further increase in the DOPA:DHPG ratio at follow-up
