The variome is the whole set of genetic variations found in populations of species that have gone through a relatively short evolution change. For example, among humans, about 1 in every 1,200 nucleotide bases differ. However, as the human species diverged only 10,000 years ago, this variation rate is comparatively small. In practice, the variome can be the sum of the single nucleotide polymorphisms (SNPs) of the population. The Human Variome Project seeks to compile this genetic variation data worldwide. Variomics is the study of variome and a branch of bioinformatics.
