In 2000, the major data type in RGD was rat markers, comprised of both expressed sequence tags (ESTs) and simple sequence length polymorphisms (SSLPs). The maps in 2000 included only genetic and RH maps and the cytogenetic map. In 2019, RGD stores and presents data across eight species, with genes, transcripts and proteins for all species, and variants for rat and human comprising the largest datasets. Note that RGD does not currently track rat variants across assemblies or between strains.
