The DASHR database provides the most comprehensive information to date on human small non coding RNA (sncRNA) genes, precursor and mature sncRNA annotations, sequence, expression levels and RNA processing information across 42 normal tissues and cell types in human. The content of the database derives from integrating annotation data with curation, annotation, and computational analysis of 187 small RNA (smRNA seq) deep sequencing datasets with over 2.5 billion reads from over 30 independent studies. DASHR contains information on over 48,000 precursor and mature sncRNA annotations in the human genome, of which 82% are expressed in one or more of the curated tissues and cell types.
