| description | Despite their hyperactivity and circling, homozygous mutant mice are able to breed and care for their young. |
| molecularNote | Mice with the mutant phenotype were discovered among G3 progeny of an ENU-mutagenized male mouse. The mutation was mapped to Chromosome 7 and identified as a G-to-T transversion in the second of the 4 exons of this gene, resulting in substitution of arginine for leucine at position 48 of the 258-amino acid protein. |
