Abstract

A new autosomal recessive mouse mutation characterized by deafness and circling behavior was recovered during mutagenesis experiments with chlorambucil (CHL). On the basis of allelism tests and linkage analyses, this mutation appears to represent a new allele of waltzer (v) that maps to mouse Chromosome (Chr) 10. We have designated this new allele, Albany waltzer (vAlb). A high-resolution map of the region around v was constructed from data from two intersubspecific backcrosses involving Mus musculus castaneus. The analysis of 648 backcross mice has allowed vAlb to be localized 1.1 +/- 0.4 cM distal to D10Mit60 and 0.2 +/- 0.2 cM proximal to a cluster of four markers, D10Mit172, D10Mit112, D10Mit48, and D10Mit196. An independent backcross was used to confirm the map order and distances in the vAlb backcross. The two linkage maps were consistent, indicating that the lesion in vAlb, which is presumed to be a deletion based on the known action of CHL, is small and has not significantly altered the map at this level of detection. Additionally, three genes (Ros1, Grik2, and Zfa) were eliminated as possible candidates for vAlb, and several SSLP markers were separated genetically.
