These markers, as genotyped on S.LEW RNO1 congenic strains, are located between D1Rat211 and D1Rat12. The current rat genome assembly places the genomic fragment from D1Rat211-D1Rat12 on RNO17. Celera assembly of the rat genome confirms our mapping of the location of the fragment from D1Rat211-D1Rat12 as being on Chromosome 1 and not on Chromosome 17
