Disruption of the reelin gene by partial deletion causes the neurological phenotype known as reeler. Here we report the cloning and sequencing of the reelin breakpoint region from the Jackson reeler strain (rl). Based on this sequence, we developed a polymerase chain reaction screen that allows the identification of mutant mice prior to the appearance of the phenotype. The assay also permits discrimination of heterozygous from wild-type mice. These findings provide a strategy for the characterization of the early anatomical and physiological consequences of the reeler mutation.
