The original Human Genome Project map of the human genome was largely based on the DNA of one mixed-race man from Buffalo, with inputs from a few dozen other individuals, mostly of European descent. Now, researchers have released draft results from an ongoing effort to capture the entirety of human genetic variation…

More than 20 years after the first draft genome from the landmark Human Genome Project was released, researchers have published a draft human ‘pangenome’ — a snapshot of what is poised to become a new reference for genetic research that captures more of human diversity than has been previously available. Geneticists have welcomed the milestone, while also highlighting key ethical considerations surrounding the effort to make genome research more inclusive…

The draft genome, published in Nature on 10 May, was produced by the Human Pangenome Reference Consortium. Launched in 2019, the international project aims to map the entirety of human genetic variation, to create a comprehensive reference against which geneticists will be able to compare other sequences. Such a reference would aid studies investigating potential links between genes and disease.

The draft pangenome follows the 2022 publication of the first complete sequence of the human genome, which filled gaps that had been left by the original Human Genome Project. But unlike the original draft human genome and its successor, both of which were derived mostly from the DNA of just one person, the draft pangenome represents a collection of sequences from a diverse selection of 47 people from around the globe, including individuals from Africa, the Americas, Asia and Europe…

As we go wide on genetics, we might send microscopic birthday greetings to Christian Anfinsen; he was born on this date in 1916. A biochemist, he won the 1972 Nobel Prize for Chemistry for his research on the shape and primary structure of ribonuclease (the enzyme that hydrolyses RNA), in whihc he found that found that its shape and consequently its enzymatic power could be restored– leading him to conclude that ribonuclease must retain all of the information about its configuration within its amino acids.
