The genotype-phenotype relationship defines evolution in the long run and human health day to day. Because it is rooted in randomness and cryptic selection forces exerted over individuals but mirrored in DNA, this relationship seems intractably complex. Surprisingly, when we frame it formally in fitness landscapes, we find that genes and their mutations obey quantitative rules from statistical physics with characteristic differences in health and disease. In practice, these rules consistently point to genes relevant to population risk of complex diseases, as examples in cancer, autism, Alzheimer’s and diabetes will show.
