Horse genome

Mapping the horse genome may also assist in the development of expression arrays to improve treatment of equine lameness, lung disease, reproduction, and immunology.

[2] This allowed creation of a catalogue of one million single nucleotide polymorphisms (SNPs) to compare genetic variation within and between different breeds.

Sugar's genome, sequenced with newer techniques, had 3 million genetic variants from Twilight's, notably in genes governing sensory perception, signal transduction, and immunity.

[5] One result of the mapping of the horse genome was locating the mutation that creates the Leopard complex (Lp) spotting pattern seen in breeds such as the Appaloosa.

[7][8] As this disorder also afflicts humans, a researcher and lead author from the Broad Institute stated, "This demonstrates the utility of the horse for disease gene mapping.
