The recent discovery of an X-linked mutation to the gene MTM1 in Rottweilers led to the addition of a genetic test for X-Linked Myotubular Myopathy to the CombiBreed webshop.

Myotubular Myopathy in the Rottweiler is a severe muscle disorder that often requires euthanasia. Affected puppies typically start displaying poor muscle growth and progressive weakness between 7 and 13 weeks of age. They behave and eat normally, but tire easily and have difficulty raising their heads or standing. Cold and stress worsen symptoms, which also increase in severity over time often requiring euthanasia.

The new DNA test for X-Linked Myotubular Myopathy is now available as a single test with test number H776, or as part of the ComiBreed Rottweiler pack (test number H577).
