there is no cure for the disorder, Animal Genetics has developed
a simple DNA test to detect a single nucleotide polymorphism (SNP)
mutation with a high degree of association to this disorder.
Animal Genetics offers DNA testing and detection of the gene mutation responsible for Hereditary Equine Regional Dermal Asthenia (HERDA) also known as hyperelastosis cutis (HC).
Collect sample by pulling (not cutting) 20-30
mane or tail hairs with roots attached. It is important that you
pull the hairs and confirm that the actual root of the hair is being
collected. The root contains the genetic material of your horse
that is needed for DNA testing. Therefore, cut hairs do not provide
an adequate sample of your horse. Place the collected hairs of each
horse in a separate zip-lock bag labeling the bags accordingly with
the horses name or identification number. Download and complete
a submission form for each sample and send along with
payment to Animal Genetics for testing.
Results are given using the following symbolic
horse carries two copies of the HERDA gene and is homozygous
for HERDA. The horse is affected with the HERDA genetic disorder.
the normal and HERDA alleles were detected. Horse tested heterozygous
for HERDA and is a carrier of the HERDA gene.
tested negative for the HERDA gene.
