But 0.1 per cent contains variations that reflect our individual ancestry.Īnalysis of the 47 samples by scientists in the Human Pangenome Reference Consortium found 119 million new variations in the genetic code and 1,115 repeated sections of DNA that contain genes. “But we now understand that having just one map of a single human genome cannot adequately represent all of humanity.”Īround 99.9 per cent of the three billion letters in our genetic code are common to all humans, binding us together as a species. This is important because even among organisms that are considered to be members of the same species, there can be significant differences in their genetic make-up.įor example, some bacterial species have been found to have as much as 25 per cent of their genes varying between different strains, while humans share about 99 per cent of theirs. It includes all of the genes and genetic variations that are found within a population. What is a pangenome?Ī pangenome aims to capture the complete genetic diversity within a species or group of organisms, rather than an individual genome, thereby reducing the bias in genetic analysis that is inherent in using a single reference genome. It was profound in how it transformed scientific discovery and launched a powerful era in genetic medicine. Karen Miga of the University of California, Santa Cruz, added: “The original Human Genome Project was a landmark achievement. ![]()
