strain_behavior The tremor behavior was exhibited from around 3 weeks of age and inherited as an autosomal recessive trait. 1299186
strain_other Linkage analysis using intercross progeny between the myelin vacuolation (mv) rat, named after the pathologic characteristics, and normal control rat strains showed that the mv phenotypes were cosegregated with polymorphic markers adjacent to the Atrn (Attractin, formerly zi [zitter]) locus on rat chromosome 3 1299186
strain_other A test for allelism suggested that the mv mutation was a new allele in Atrn: In comparison with a marked decrease of Atrn(zi)/Arn(zi), Northern blot analysis revealed no expression of Atrn mRNA in the brain of the mv rats. Finally, a genomic deletion including exon 1 of the mv rats was detected by genomic and sequence analyses. Discovery of the rat null mutation Atrn(mv), different from Atrn(zi), provides a new animal model for studying the functions of the attractin protein. 1299186
strain_phys_biochem The mutant rats had variously sized vacuoles in the neuropil and white matter throughout the central nervous system, especially in the brain stem, cerebellum, and spinal cord. Ultrastructurally these vacuoles mainly consisted of splitting of myelin lamella both in the periaxonal and intermyelinic spaces. 1299186
strain_reproduction Although affected rats are fertile for both sexes, it is recommended to use heterozygous males and females for mating. 1299186
