There are all sorts of findinigs but they do not paint any consistant picture.
For instance, some studies show high activity of the serotonin transporter, ie excessive serotonin uptake, but other (probably an equal number of) studies have found diminished serotonon uptake. Some studies have found altered levels of serotonin binding, while others have not.
Some studies have found exaggerated responces to tryptophan depletion while others have not. Some have found altered monoamine oxidase function while others have not. Some have found reduced metabolites of serotonin 5-HIAA while other have not. (Keep in mind that even if 5-HIAA levels are low, serotonin uptake inhibitors and MAOI's actually decrease this further)
