Genetic mapping reveals complex traits draw more heritability from intergenic DNA
Schizophrenia, height, cholesterol. Each has its own genetic signature.
AI Summary
Schizophrenia, height, and blood cholesterol each have distinct genetic signatures composed of DNA variants that differ between individuals. Some traits, like cholesterol levels, are influenced by a relatively small number of variants. Others, such as schizophrenia, involve many thousands of variants, each contributing a very small effect. This extensive involvement of numerous variants is referred to by geneticists as polygenicity.
