A study led by Alfonso Valencia, Vice-Director of Basic Research at the Spanish National Cancer Research Centre (CNIO) and head of the Structural Computational Biology Group, and Michael Tress, researcher at the Group, updates the number of human genes -those that can generate proteins- to 19,000; 1,700 fewer than the genes in the most recent annotation, and well below the initial estimations of 100,000 genes. The work, published in the journal Human Molecular Genetics, concludes that almost all of these genes have ancestors prior to the appearance of primates 50 million years ago.

"Our figures indicate that the differences between humans and primates at the level of genes and proteins are very small," say the researchers.
