* Note that the new data curation into the database is an ongoing process. Lower number of current/recent years data counts may simply be a reflection of time lag depending on our curator resources and work-loads.

NOTE: On this site, the term "QTL" may have collectively included quantitative loci, SNP associations, and eQTL data.
