Our DNA test for Centronuclear Myopathy is ideal for breeders and owners who want the reassurance of genetic health testing.

The guideline turnaround time for single tests is approximately 10-12 working days after the swab arrives at the lab.

If you need more than two tests it is often more cost-effective to order the relevant breed package.


Centronuclear Myopathy (CNM) is a reduction in muscle fibres causing muscle weakness, abnormal posture and gait, and exercise intolerance and collapse. Symptoms are variable but dogs are generally weak by five months of age and progression of the disorder ends around one year.

Centronuclear Myopathy is an autosomal recessive condition caused by a mutation in the HACD1 gene.


This test is also included in the following breed packages:

  • Australian Labradoodle
  • Cockerdor
