RefSeq and LocusLink growth over a 1-year period. (A) The number of RefSeq records for human, mouse and rat for mid-September of 1999 and 2000. These numbers include genes for which multiple reference sequences are provided to represent splice variants and their products. As of September 2000, 10 301 human reference sequence mRNAs (and their corresponding proteins) are provided for 9954 genes. The number of human RefSeq records in three categories is also indicated (Hs, human); Genome Annotation reference sequence numbers are not included. Rat, mouse and predicted human RefSeq records became available after September 1999. (B) Loci available in LocusLink for September of 1999 and 2000. Mouse, rat, zebrafish and fruit fly genomes were added after September 1999. Of the 17 214 known human loci, 14 103 have some associated sequence data (including ESTs), and 9954 loci have at least one mRNA and protein reference sequence.
