WICGR Mouse RH Map Home Page

The Whitehead Institute/MIT Center for Genome Research is committed to producing a high-density radiation hybrid map of the mouse genome. We will update the RH maps on our public web server on the 15th of each month.

Whitehead Mouse RH Data

Release 4 text file is a large tab delimited text file containing the following fields: chromosome, marker locus name, lab assay name, genbank accession number, framework identifier or placement identifier, cumulative centiMorgan position from genetic map, cumulative centiRay position from RH map, intermarker centiRay distance from RH map, forward primer sequence, reverse primer sequence, consensus RH vector, brief EST description.

Release 4 FASTA file is a large text file containing the marker name followed by the marker's origin clone sequence or unigene cluster assembly sequence.

Whitehead T31 hybrid order is a list of which hybrids we utilized (in order) to create the consensus vector for mapping.

Release 4 Radiation Hybrid Maps

The framework markers in this release are identical to those in release one. Placement markers were positioned in their most likely position within respective genetic linkage groups within the framework reference map if they showed strong pairwise linkage (lod>9).

The following pictures represent the radiation hybrid maps for the 20 mouse chromosomes. The GIF and PICT images have framework markers printed in black and placement markers printed in red. The centiRay units shown represent inter-marker distances. The text versions of each map contain four columns. Column one is the marker name. Column two is the inter-marker distance in centiRays. Column three is whether the marker is a framework or a placement marker and if a placement marker its lod for placement confidence is shown. The fourth column is the consensus RH vector generated for that marker.
