Phenotypes

In a remarkable indication of the power of whole-genome sequence analysis, Daetwyler et al. (2014) identified a causal mutation for this disorder in Holstein Friesian cattle as a missense mutation (g.32475732G>A [UMD3.1 reference sequence]; p.Gly960Arg, omia.variant:223) in the COL2A1 gene (which encodes the alpha-1 chain of type II collagen), by comparing the sequence of only two affected calves with sequence from bulls in the 1000-bull-ge...

Because of the obvious homology of this disorder with the homologous human disorder, Drögemüller et al. (2001) proposed that the bovine disorder be called by the name of its human homologue, which is now done in this catalogue. The earlier names are listed here as species-specific names [Frank Nicholas 20 June 2002].
