Test for Hereditary Equine Regional Dermal Asthenia (HERDA)

技术优势

UC Davis researchers have developed a test which breeders could use to screen their breeding stock for carriers, to reduce or eliminate the possibility of producing affected horses.

技术应用

This test provides both a means of diagnosing the disease prior to clinical signs as well as a means for breeders to avoid producing affected animals.

详细技术说明

Hereditary Equine Regional Dermal Asthenia (HERDA) is an inherited skin disease found in the American Quarter Horse population. There is no treatment for the disease and the severe lesions associated with HERDA most often result in the euthanasia of affected horses. Researchers at the University of California, Davis have developed a test for identifying carriers of HERDA. Furthermore, this test can detect affected animals prior to clinical signs. Homozygosity mapping was used to isolate the locus. Microsatellites and gene-based single nucleotide polymorphism (SNP) markers were used to reduce the critical interval around the disease locus to a small region, predicted to contain 20 known genes and approximately 2.0-2.5 MB of DNA based on comparisons with other mammalian genomes. A SNP within the coding region of one of the genes within this critical interval was discovered within the affected HERDA population and can be used as an informative marker for identifying unaffected carriers of the disease.
