Bear, a 5 month old Lab, was rescued by LEARN in April 2016. He was surrendered because he was having difficulty standing. LEARN had genetic testing done which revealed that Bear has CNM, Centronuclear Myopathy, an inherited disease resulting from a mutation in a gene (PTPLA). This condition is also known as type II muscle fiber deficiency, autosomal recessive muscular dystrophy and hereditary myopathy.
Bear received a pair of recessive genes from his parents and as a result is missing muscle fibers. His prognosis is poor. Bear will never recover from this disabling disease. There is no cure and no treatment. Dogs usually become non-ambulatory within the first year of life. Respiratory complications can also develop.
In spite of his physical limitations, Bear has a wonderful personality. Bear's foster family is determined to keep him comfortable for as long as possible.
This diagnosis is very sad news for Bear. It is doubly sad to think there may be others in the litter with the same condition. About 25% of the litter will contract the disease when both parents are carriers. Another 50% of the litter will be carriers and could sire affected offspring if bred with another carrier.
Responsible breeders test their dogs for CNM prior to breeding. If you are considering getting a Labrador puppy from a breeder, please make sure the breeder has tested the parents for this gene.
