Polysaccharide Storage Myopathy type 2 (PSSM2)


EquiSeq Has Developed Tests for the Predisposition to PSSM2/MFM

Researchers at EquiSeq have developed tests for genetic variants that predispose a horse to Polysaccharide Storage Myopathy type 2 (PSSM2) or Myofibrillar Myopathy (MFM), a subtype of PSSM2. These tests identify horses at risk for developing PSSM2/MFM before they show any symptoms.

Purchase a Horse with Confidence

You deserve a lifetime with your best friend. Avoid the heartache and expense of a devastating late-onset disease with EquiSeq's tests for PSSM2/MFM.

Some horses show no symptoms of PSSM2/MFM until the age of 7 - 10 years or later.

Ask your veterinarian for EquiSeq's PSSM2/MFM tests as part of your pre-purchase exam, or ask the current owner to order tests.

Test Your Current Horse

If your horse has symptoms of exercise intolerance (tying up, shifting lameness, stiff or sore muscles after exercise, staying camped out after urinating, coffee-colored urine, muscle wasting), you can't manage your horse's condition without a diagnosis. You and your veterinarian need to work together.

Ask your veterinarian for EquiSeq's PSSM2/MFM tests as part of getting an accurate diagnosis.

Don't Breed Without Testing

Horses can be bred years before most will show any symptoms of PSSM2/MFM. Testing both stallion and mare before breeding will let you breed with confidence.
