The SCID/BLAJ mouse model of dysferlinopathy was created by Dr. Ivan Torrente by backcrossing dysferlin deficient BLA/J mice onto the SCID strain while selecting for the retrotransposon insertion in intron 4 of the dysferlin gene, as well as the absence of specific B- and T- lymphocyte markers (CD4, CD8, and CD19) in cells isolated from peripheral blood. The result is a dysferlin deficient animal model that is also deficient in B and T lymphocytes, and thus more amenable to transplantation studies. Dr. Torrente has yet to publish an initial characterization of these animals, but has generously made them available to the dysferlin research community.
An ETn retrotransposon (5-6kb) is inserted in intron 4 of the dysferlin gene.
