Few things generate as much excitement as the arrival of a new puppy in the family. However, that joy can turn into distress if, in their first few months of life, the animal begins to show extreme muscle weakness, a lack of coordination, delayed growth, or unexplained neurological failures.
Often, behind this premature deterioration lie lysosomal storage diseases and glycogen storage diseases. These are a group of severe monogenic metabolic disorders caused by the malfunction of specific cellular enzymes, preventing the body from properly processing sugars, fats, and other molecules.
Cellular collapse: Impact on metabolism
To understand these conditions simply, imagine that lysosomes are the cells' "recycling system". When the enzymes fail, this system gets blocked. The substances that the body should break down accumulate in a toxic way, causing a collapse of the cellular machinery.
These warning signs usually manifest very early and affect critical organs:
- Rapid degeneration of the central nervous system.
- Severe deterioration of muscle tissue.
- Severe alterations in the liver.
Genetic identification
The diversity of these metabolic disorders requires scientific precision.
With dog DNA testing and cats from Koko Genetics, we offer preventive genetic information on certain variants associated with inherited diseases:
- Lysosomal storage disease (dogs): Analyses variants associated with lysosomal alterations that can affect the nervous system.
- Neuronal Ceroid Lipofuscinosis 4A (NCL4A): A severe disorder associated with a variant in the ARSG gene, affecting breeds such as the American Staffordshire Terrier.
- Pompe disease (Glycogen storage disease type II): An inherited pathology resulting from an alteration in glycogen storage (GAA gene).
- Glycogen storage disease type IV (cats): Detects variants associated with alterations in glycogen metabolism related to neuromuscular and cardiac failures in felines.
As these are inherited, recessive, and degenerative conditions, an effective way to prevent a puppy from being born with these diseases is preventive genetic screening.
The DNA test is a useful tool to better understand an animal's genetic information and make responsible decisions regarding their health and welfare.
