Simple sequence-length polymorphisms (SSLPs) are also known as microsatellite DNA. SSLPs consist of 1 - 6 simple nucleotide repeat sequences, highly polymorphic in repeat length among strains. They are often used as genetic markers for genotyping.
The annotation data file, RGD_SSLP.gff, was downloaded from
      
ftp://rgd.mcw.edu/pub/RGD_genome_annotations/V3.1/GFF_files/
and processed to create two UCSC Genome Browser tables -- rgdSslp and
rgdSslpLink -- to enable this track.
Thanks to the RGD for providing this annotation. RGD is funded by grant HL64541 entitled "Rat Genome Database", awarded to Dr. Howard J Jacob, Medical College of Wisconsin, from the National Heart Lung and Blood Institute (NHLBI) of the National Institutes of Health (NIH).
