Description
Mice homozygous for the scrambler spontaneous mutation (Dab1scm) are recognized by an unstable gait and whole-body tremor. The cerebella of 30-day-old scrambler homozygotes are hypoplastic and devoid of folia; however, neither seizures nor abnormal brain wave patterns have been observed. Scrambler is similar to the reeler mutation in phenotype and pathology and, like reeler, probably results from defective neuronal migration. Female homozygotes mate and breed. Homozygous scrambler mutants have an ataxic gait which in the male may be contributory factor in the failure to mate. Normal life span for both sexes.

The following phenotype information may relate to a genetic background differing from this JAX® Mice strain.

Dab1scm/Dab1scm

        involves: C3H * C57BL/6J
  • nervous system phenotype
  • abnormal retinal rod bipolar cell morphology (MGI Ref ID J:71970)
    • density of cells is decreased, indicating a decreased number of rod bipolar cells compared to controls
  • vision/eye phenotype

  • abnormal retinal rod bipolar cell morphology (MGI Ref ID J:71970)

Genes & Alleles

Gene & Allele Information

Allele Symbol Dab1scm
Allele Name scrambler
Allele Type Spontaneous
Common Name(s) scm;
Strain of OriginDC/LeJ
Gene Symbol and Name Dab1, disabled homolog 1 (Drosophila)
Chromosome 4
Gene Common Name(s) AI956902; C630028C02Rik; RIKEN cDNA C630028C02 gene; expressed sequence AI956902; scm; scr; scrambler; yot; yotari;
Molecular Note Transcripts produced from this allele show abnormal splicing and are predicted to produce a truncated protein. Sequence analysis revealed that the larger scrambler transcript contains 1.5 kb of intracisternal A particle retrotransposon (IAP) sequence inantisense orientation. Previous mapping studies detcted an IAP particle that failed to recombine with the Dab1 locus. Thus, it appears that abberrant splicing has incorporated the IAP element in the coding region of the gene. [MGI Ref ID J:42628] [MGI Ref ID J:43504]

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
