An explanation of the use of 'D_Dcr' codes in Roopenian colony strain names
In producing and characterizing many of our congenic strains, we relied heavily on SSLP genotyping markers which spanned regions of dinucleotide repeats, similar in idea to MIT markers.For listing on official data collating sites like MGI, we are required to assign our new markers boring, relatively uninformative names such as 'D9Dcr1'. For our purposes, we choose to use a lab alias for each marker which represents its position in Megabases (Mb). Thus D9Dcr1 we call D9Dcr63.401, which tells us that the marker amplifies a product on mouse chromosome 9 at ~63.401 Mb. The reason MGI will not accept such a name is that positions on the genome map tend to shift as we learn more. Positions represented in all of our marker names are currently based on Ensembl build 36, release 43, February 2007.
When we give a congenic name such as B6.C-(D9Dcr 96.207-D9Dcr100.983)<c>/(R42)Dcr, the name tells us that, of the markers available
