Genome Reference Consortium

The Genome Reference Consortium (GRC) is an international collective of academic and research institutes with expertise in genome mapping, sequencing, and informatics, formed to improve the representation of reference genomes. At the time the human reference was initially described, it was clear that some regions were recalcitrant to analysis with existing technology, leaving gaps in the known sequence.
