Variome

The variome is the whole set of

single nucleotide polymorphisms (SNPs), indels, and structural variation (SV) of a population or species. The Human Variome Project seeks to compile this genetic variation data worldwide. Variomics is the study of variome and a branch of bioinformatics
.

Ethnic variomes

The human variome can be subdivided into smaller ethnicity specific variomes. Each variome can have a utility in terms of filtering out common ethnic specific variants in the analyses of cancer normal variants filtering for more efficient detection of somatic mutations that can be relevant to certain anti-cancer drugs. KoVariome is one such ethnic specific variome where the project uses the term variome to denote their identity and connection to the concept of the broader human variome. KoVariome founders have been affiliated with HVP since early days of HVP where Prof. Richard Cotton initiated various efforts to compile the human variome resources.

Many curated databases has been established to document the impact of clinically significant sequence variations, such as dbSNP [1] or ClinVar.[2] Similarly, many services have been developed by the bioinformatics community to search the literature for variants.[3] ‌

Etymology

The blend word 'variome' is from genetic variant (“a version of a gene that differs from other versions of the same gene which may or may not have an effect on human health”) and the suffix –ome (“the complete whole of a class of substances for a species or an individual”). ‘Variomics’ (which appeared in the literature before ‘variome’) was first coined by Professor Richard ‘Dick’ Cotton in 2002 to describe (“The systematic study of the effect of genetic variation on human health”). ‘Variome’ has since been most commonly used in reference to the ‘Human Variome Project’ founded four years in 2006 after ‘variomics’ was first coined.

Projects

There are a number of international project studying the human variome, including the International HapMap Project and the Human Variome Project (HVP).[4] The HapMap Project aims to identify and catalog genetic similarities and differences among humans. The HVP aims to collect data on all human genetic variation. The Korean Genome Project, which aims to collect all the East Asian ethnic Korean genetic variations has produced KoVariome that contains currently over 1,000 Korean whole genome variation information.[5] Turkish Genome Project has plans to analyze genomes of 100,000 people in Turkey.[6]
