 | The Foundation Jean Dausset-Centre d'Etude du Polymorphisme Humain
(CEPH) maintains a database of genotypes for genetic markers that have
been typed on the CEPH reference family resource for linkage mapping
(Genomics 6: 575-577, 1990; Science 265: 2049-2054, 1994).
The present version of the database (V10.0 - December 2004) contains
genotypes for 32,356 genetic markers. These include data for a total of
21,480 bi-allelic markers, of which 17,512 may be assigned to dbSNP by
rs or ss numbers. V10 also contains more than 9,900 microsatellite markers.
The mean observed heterozygote frequency of all the loci in V10.0 is
0.438, and for identifiable microsatellite loci 0.698, of which 56% are
highly polymorphic (obs.het. ? 0.70).
The CEPH database now manages 6,081,570 genotypes.
We have computed 25,924,717 lod scores between all pairs of syntenic
marker loci on each pair of segregating chromosomes.
