This list excludes knockouts that are cryopreserved, difficult to breed, severely immunodeficient, or homozygous lethal. There may be additional issues related to using some of these strains. In addition to the 59 strains listed, the Jackson Laboratory has 41 knockout strains in the process of being backcrossed to B6 and 74 strains which only exist as cryopreserved stocks. Many of the congenics are clustered and represent different knockouts of the same gene or different genes in gene clusters. These overlapping congenics were included because they will have considerable utility for fine mapping QTLs in the region.
