Genetic Linkage

The Age of the Pangenome Dawns

"Pan" has several meanings.


As a noun, it refers to "a round metal container that often has a long handle and a lid."


As a verb, it means criticism, like panning a film.


Peter Pan refers to an adult who doesn't want to behave like one, from Sir James Barrie's play about the boy who didn't want to grow up


As a prefix, "pan," from the Greek, means "all, every, whole, and all-inclusive."


Sigmund Freud reportedly used the term pan-sexualism in 1914, to mean "sex as a motivator of all things."


In genetics, the human pangenome is a complete reference of human genome diversity. It is envisioned as a new type of map that represents all of the ways that the sequence of 3,054,832 billion DNA base pairs – the building blocks of a genome – vary, plus or minus a few from short repeated sequences. The depiction is so densely packed that it resembles a map of the New York City subway system.


The Human Pangenome Reference Consortium is spearheading creation of a "genome reference representation that can capture all human genome variation and support research on the full diversity of populations."
