Centronuclar Myopathy = CNM
CNM (Centronuclear Myopathy) is something that no breeder would like to have happen in their puppies and something that you can eliminate via an easy dna test. If a breeder breeds a carrier to a carrier, puppies with CNM can be produced. It just takes testing your breeding dogs to be sure you never produce this problem. Breeders should be testing their dogs. Originally called Labrador Muscular Myopathy or Hereditary Myopathy of the Labrador Retriever (HMLR) due to it being breed specific to labradors. It is a hereditary disease where the muscles of the Labrador do not develop properly. Affected pups are obvious by the time they are between three and six months of age. The pup will begin to stumble and fall when trying to walk. There are difficulties in swallowing since the muscles in the esophagus are often affected. There is no cure for the disease. CNM is a simple autosomal recessive. Please go to www.labradorcnm.com and look at the Genetics link in the left menu for charts on breeding. Consider the charts before planning a breeding.
