Genotyping results for <i>RNF34</i> and <i>KDM2B</i> mutations.

aCattle recorded as parent of affected calves. bFor this cow only one single suspicious offspring was recorded by the breeding organization and the diagnosis of this calf had not been confirmed by necropsy. Genotyping of additional flanking markers revealed that this animal did not carry the disease-associated haplotype. Therefore, the reported calf most likely represented a phenocopy and the parent is indeed free of the deleterious mutation.
