Genetic Models Of Depression Research findings

It has been clear for decades that there is a significant genetic predisposition to depression. Evidence of a genetic component of unipolar depression comes from the usual sources for genetic studies. Family studies show increased familial risk—the earlier the age of onset, the higher the familial risk—and twin and adoption studies confirm a clear genetic component, though less for community-sampled or 'neurotic' depression, suggesting a lesser biological component (Hirschfield & Weissman, 2002). What is less clear is how this genetic risk translates into the expression of depressive illness. No evidence exists for true Mendelian inheritance. The few studies finding linkage have not been replicated.
