摘要：

The wobbler mouse (genotype wr wr has been considered as an animal model for human neurodegenerative disorders. In the homozygous condition, the autosomal mutation wobbler (wr) causes a motoneuron disease and gonadal dysfunction. We have genetically mapped the wr gene, using an interspecific backcross between the laboratory strain C57BL 6J (wr/+) and Mus spretus. The expected percentage of wobbler progeny were obtained, but heterogeneous expression of the wobbler phenotype indicated the existence of modifier genes in the M. spretus genetic background. The segregation of DNA markers of known chromosomal location among wobbler progeny and unaffected mice was scored. Close linkage of wr was obtained with Erbb and Rel on chromosome 11 and the gene order cen-Nfh-Erbb-wr-Rel-Hba-Il-3 was established. Closely linked markers like Erbb provide tools for a prognostic DNA diagnosis of the wobbler disease, and thereby for its analysis by descriptive and experimental embryology. © 1992.
