Most known genome browsers, such as NCBI genome  and Craig Venter's genome browsers , were built for consensus sequences from multiple individuals to construct a reference human genome. Examples of haplotype genome browsers are NCBI, UCSC , Ensembl , and Venter genome browsers. Recently, the first Asian (Chinese) diploid genome database was published, containing analysis and browsing facilities [5, 6]. There are a number of general purpose genome annotation servers. They include Entrez Gene , Ensembl genes, OMIM  disease associations, HapMap , SNPedia , and genetic variations of several individual genomes such as Venter , Watson , YH (Chinese), and NA18507 (Yoruba) . We have developed an individual genome variation analysis and browsing server (Gevab) for the first Korean personal genome sequence (KOREF).
This server is useful to analyze a diploid human genome produced to study the complex features of human genetic variations. The system integrated multiple variation information such as Venter, Watson, YH, dbSNP, and HapMap genotypes as well as gene information. Hence, users can comparatively study the genotypes in human. Gevab also provides information for SNPs, short indels, and SVs on the KOREF genome. Gevab has two parts: genome variation analysis and genome mapping.
