Primary Databases
International Nucleotide Sequence Database (INSD) consists of the following databases.
DDBJ
DNA Data Bank of Japan (DDBJ) provides sharing and analysis services for data from life science researches and advances science.
EMBL
European Bioinformatics Institute (EMBL) is a molecular biology research institution supported by 22 member states, four prospect and two associate member states.
GenBank
National Center for Biotechnology Information (GenBank) is the NIH genetic sequence database, an annotated collection of all publicly available DNA sequences.
The three databases, DDBJ (Japan), GenBank (USA) and European Nucleotide Archive (Europe), are repositories for nucleotide sequence data from all organisms. All three databases accept nucleotide sequence submissions, and then exchange new and updated data on a daily basis to achieve optimal synchronisation between them. These three databases are primary databases, as they house original sequence data. They collaborate with Sequence Read Archive (SRA), which archives raw reads from high-throughput sequencing instruments.
Secondary Databases
RefSeq
The Reference Sequence (RefSeq) database[1] is an open access, annotated and curated collection of publicly available nucleotide sequences (DNA, RNA) and their protein products.
OMIM
OMIM is Online Mendelian Inheritance in Manauthored and edited at the McKusick-Nathans Institute of Genetic Medicine.
HapMap
The International HapMap Project was an organization that aimed to develop a haplotype map (HapMap) of the human genome, to describe the common patterns of human genetic variation.
23andMe
23andMe is a privately held personal genomics and biotechnology company based in Mountain View, California. The company is named for the 23 pairs of chromosomes in a normal human cell.
