not sure why the downvotes?

I predict it would be possible to quantify the effects objectively, as a thought experiment: assuming functional proteins, gene regulation is about binding affinities of cellullar chemical species to promoter regions, so 200k promoter regions x number of chemical species present in humans give us the number of binding affinities that describe the behavior of human cells (essentially all cell types excluding some germ-line cells, but including brain cells).

the thought experiment: apart from ethics nothing prevents humanity from going to all the remaining wild-type or near wild-type humans (when did 5% of the local population start wearing glasses? as a measure of wild-type-ness), and collecting as many individual genomes as possible, for a reference data set for the table of binding affinities. For each individual genome there is 1 table of binding affinities. Now we start averaging the value of each location in the table by averaging this table over all the collected genomes.

So theoretically we could collect the bulk of the gene regulatory information / skills encoded in the genome for wild-type humans. Next we can traverse the medical literature on autism and collect all the reported or suggested features, survey answers, diagnostic indicators for the full autism spectrum, and for each population in such a separating indicator, fetch example genomes from the purported indicated and unindicated groups, and compare their averaged binding affinity tables until you resolve or exclude any genetic correlation.

Or people downvote because I can't wait for science to ... progress?
