National Center for Biotechnology Information (NCBI)The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.
NCBI provides a number of resources. Such as AceView which provides a curated, comprehensive and non-redundant sequence representation of all public mRNA sequences, as well as ClinVar which collects submissions from clinical testing labs, researchers, locus-specific databases, expert panels, and professional societies. Others include dbVar and dbSNP which are databases of genomic and SNP structural variation that allows users to search, view, and download structural variation data from submitted studies on several species. There is also GeneBank which is a collection of annotated genetic sequences, and Gene Expression Omnibus (GEO) which is a public functional genomics data repository. It also includes HapMap which helps researchers find genes associated with human disease and PubChem which is a database of chemical molecules and their activities against biological assays.
