Interpretive Summary: The spotted locus is responsible for several phenotypically distinguishable piedald patterns in cattle, including Hereford, or white face (SH), lineback (SP), and recessive spotting (s), in addition to non-spotted (S+). In a backcross mapping population, the S locus has been mapped by genetic linkage to bovine chromosome 6, showing complete linkage with microsatellite marker CA028. This region corresponds comparatively to a region on mouse chromosome 5 which houses several coat color mutations, among which homology is possible with Hardy- Zuckerman 4 feline sarcoma viral oncogene homology (KIT), Patch (Ph), and Rump white (Rw). Mutations at these loci resemble mutations at the bovine S locus in both phenotype and mode of inheritance. Data are presented which show genetic linkage between the bovine S locus and microsatellite markers on chromosome 6. Candidate genes for the bovine S locus are discussed.
