Humans are not Mendelian pea plants
"There is not one clear genetic signifier for most serious diseases, as the industry appeared to promise."
This should also undermine those people who argue that one or two genes underlie criminal behavior, or genius, or artistry, or whatever fad of the day is being said to be genetic. Funny, but it turns out to be more complicated than the simplistic "criminal gene" or "genius gene" - surprise! Nature and biology are complex! Humans are not Mendelian pea plants - most traits are combinations of lots of genes (and nurture too!)
