Did you know there is a new genetic disorder, linked in American Quarter Horses?

❗️Equine Juvenile Spinocerebellar Ataxia (EJSCA) is an inherited neurologic disease that causes ataxia in foals.❗️

🟥Phenotype: Affected foals develop ataxia, or incoordination, between 1 and 4 weeks of age. The disorder progresses within a few days until affected foals are unable to stand without assistance.

🟥Mode of Inheritance: Autosomal recessive

🟥Alleles: N = Normal/Unaffected, JSA = juvenile spinocerebellar ataxia

Explanation of results:
• Horses with N/N genotype will not have equine juvenile spinocerebellar ataxia and will not transmit the JSA allele to their offspring.
• Horses with N/JSA genotype will not have equine juvenile spinocerebellar ataxia, but are carriers. They may transmit the JSA allele to 50% of their offspring. Breedings between two carriers result in a 25% chance of producing an EJSCA-affected foal.
• Horses with JSA/JSA genotype will have juvenile spinocerebellar ataxia.

Watch our embryologist, JoAnne Stokes, perform an ICSI procedure. 🧐

The intracytoplasmic s***m injection (ICSI) procedure involves micro-injection of a single s***m cell into the ooplasm of a mature oocyte. The fertilized oocyte is returned to an incubator in an effort to support development into an embryo reaching transferrable quality, typically within 6-8 days.

Once embryos are obtained and deemed viable, they can be:
👉Fresh transferred into recipient mare
👉Auto-transferred back into donor mare
👉Shipped to another embryo transfer facility
👉Frozen for use at a later date
