X-Linked Myotubular Myopathy

What is XL-MTM?

This is a degenerative muscle disease first characterized in the Labrador Retriever. Affected dogs present as puppies with failure to thrive and weakness; this rapidly progresses to difficulty eating and breathing. XLMTM stems from a deficiency in the protein myotubularin, which is thought to be important for the development and maintenance of muscle cells. Loss of myotubularin causes muscle fiber damage and death, leading to replacement of the muscle mass with scar tissue. Unfortunately, there is currently no treatment for XLMTM.
