Microsatellite mapping of the bovine roan locus: a major determinant of White Heifer disease.[Bearbeiten | Quelltext bearbeiten]

  • Charlier C, Denys B, Belanche JI, Coppieters W, Grobet L, Mni M, Womack J, Hanset R, Georges M: Microsatellite mapping of the bovine roan locus: a major determinant of White Heifer disease. Mamm Genome. 1996 Feb;7(2):138-42, PMID 8835531

In the Belgian Blue Cattle breed, coat color variation is mainly under the influence of a single autosomal locus, the roan locus, characterized by a pair of codominant alleles: r+ (black) and R (white). Heterozygous r+R animals have intermingled black and white hairs, yielding the "blue" phenotype typical of the breed. Major interest for the roan locus stems from its pleiotropic effect on fertility, owing to the critical role of the R allele in the determinism of White Heifer Disease. We describe the linkage mapping of the roan locus to bovine Chromosome (Chr) 5, in the interval between microsatellite markers BPI and AGLA293, with an associated lodscore of 11.2. Moreover, we map a candidate gene, the Steel locus coding for the mast cell growth factor, to bovine Chr 5.

Schwein[Bearbeiten | Quelltext bearbeiten]

  • Schwein: In the pig, we have described seven MC1R alleles controlling four different coat color phenotypes (wild type, dominant black, black spotting, and recessive red). The most interesting allele is the one causing black spotting because it carries two causative mutations, a frameshift and a missense mutation. The frameshift mutation is somatically unstable, and the black spots reflect somatic reversion events restoring the reading frame.
  • Schwein: A previous study indicated that a missense mutation (D298N) in pig MC4R has an effect on fatness, growth, and feed intake. We could not confirm this association using an intercross between the wild boar and Large White domestic pigs, but it is possible that our F2 generation was too small to detect the rather modest effect reported for this polymorphism.
