The invention relates to the field of medical diagnostics. More specifically, the invention relates to methods to diagnose or screen for inflammatory conditions or
disease, including auto-inflammatory
disease and affective disorder, in a subject, preferably a human subject, by assaying for a marker for an inflammatory
disease. Provided is a method to diagnose, screen for or predict the development of an affective disorder (AD), preferably bipolar disorder (BP), in a subject, the method comprising determining the level of at least one, preferably at least two, more preferably at least three, most preferred at least four, AD-specific
gene product(s) in a biological sample isolated from the subject, preferably
peripheral blood monocytes, wherein the
gene is selected from the group comprising ATF3,
