Description
What is Centronuclear Myopathy?
Centronuclear Myopathy (CNM) is an inherited autosomal recessive disorder. Affected pups start with significant weight loss at just a few weeks of age. Within a few months, there is a loss of tendon reflexes, awkward gait and exercise intolerance. Our DNA test for Centronuclear Myopathy gives Labrador breeders an accurate, convenient, and affordable tool to help them avoid producing CNM-affected offspring and significantly reduce the gene frequency in future generations.
This test is validated for Labrador Retrievers only.
Understanding Results
There are 3 possible genotypes reported for Centronuclear Myopathy:
- CLEAR: those having 2 copies of the normal allele and appear to be normal
- CARRIER: those having 1 copy of the normal allele and 1 copy of the mutation, but appear to be normal
- AFFECTED: those having 2 copies of the mutation and are likely begin to show weight loss, muscle weakness and exercise intolerance after a few months of age
