Release Five of the Whitehead Institute/MIT Genome Center Genetic Map of
the Mouse is now available.  This map consists of randomly-chosen simple
sequence length polymorphisms (microsatellites) that can be analyzed
using the polymerase chain reaction, as described in Dietrich, W., et.
al., Genetics 131:423-447 (1992).

Currently the released map contains 3011 markers.  The markers fall into
20 linkage groups spanning approximately 1400 cM with an average spacing
of less than 0.5 cM.

This data can be obtained in two different ways.

1.  Via anonymous ftp to  Log in as "anonymous" and
use your e-mail address as password.  The release can be found in the
directory /distribution/mouse_sslp_release/jan94/.  The file "README"
describes the file format and gives other information about the map.

2.  Via internet e-mail using a database e-mail server. Using this
service you can obtain locus and assay names of mapped SSLPs, the
forward and reverse primer sequences, the genotypes of the loci on the
mapping cross, the sizes of the PCR products on selected standard inbred
strains, and other useful information.  The database can be queried for
markers meeting a number of different criteria.  For example, you can
ask for markers by name, by chromosome, or by position on the map.  You
can even request a list of markers that are polymorphic between two
mouse strains.

To obtain copies of the most current query forms, send a message to
"genome_database at" with either a subject line or body
text of "help". You will receive instructions and a query form by return
mail.  Just fill out the form, send it to
"genome_database at", and the answer to your query will
be mailed back automatically.

This project is an ongoing one.  As new markers are added to the map
they will be released on a quarterly basis on approximately the
following schedule:

1 April 1994
1 July 1994
1 October 1994
1 January 1995
