Thank you for being the only one to understand my point (which you pointed out in your second paragraph) and not just knee-jerk down voting. My account was automatically censored by the HN algorithm for exploring a controversial viewpoint.
As for the bio-marker there are a number of things that could be looked at: flue/bascterial infection during pregnancy, age of father, anti bodies in mother, rheumatoid arthritis genetic markers in mother, asthma markers.
I have to disagree that it is a narrow possibility. So much of the future of a child is determined during the formative years. Intentionally aggravating an at-risk child's immune system over and over again is something that needs to be very closely researched. To not do so at this point given all that we know seems very unethical.
