A certain contribution will be genetic (complex, not a single gene). A certain contribution will be from in utero environmental exposure (mother's hormone milieu, infection, mother's immune response, placenta, etc), and then a certain percentage will be post-birth measurable environmental exposure (chemicals, toxins, formula feed, etc). And then a percentage will be more complex, more difficult to understand and measure environmental factors.
Ironically, the formulation above is the same formulation used in describing complex "unsolved" diseases, like schizophrenia.
