Manx syndrome, also known as sacrocaudal dysgenesis or sacrocaudal agenesis, is a condition that affects the hind legs, urinary bladder, and colon of tailless cats, primarily in the Manx breed. This syndrome arises due to abnormalities in the development of the spine and spinal cord, leading to various neurological problems.
Inheritance
Manx syndrome is inherited as an autosomal dominant trait in Manx cats. This means that the trait can be passed down from just one parent carrying the gene, and offspring will inherit the condition. However, the degree of spinal malformation can vary, and not all tailless Manx cats will exhibit severe neurological problems.
Signs and Symptoms
The severity of Manx syndrome can vary widely among affected cats. Some may exhibit mild or no neurological changes, while others may experience severe deficits. Signs typically become noticeable when kittens begin to walk, which can occur weeks to months after birth. Common symptoms and signs of Manx syndrome include:
- Taillessness: Tailless or partially tailed appearance.
- Urinary or Fecal Incontinence: Inability to control urine and feces.
- Secondary Urinary Tract Infections: Frequent urinary tract infections due to incontinence.
- Urinary Scalding and Staining: Skin irritation and staining due to prolonged contact with urine.
- Constipation: Difficulty passing stools.
- Partial Paralysis of Hind Legs: Hind-end paralysis to varying degrees.
- Bunny Hopping Gait: Abnormal hopping or dragging of the hind legs.
- Lack of Sensation: Diminished sensation in the hind legs and around the anus and urethra.
- Unusual Stance: Walking on the entire foot instead of just the toes.
- Rectal Prolapse: Protrusion of the rectum.
- Megacolon: Abnormal dilation and loss of contractility of the colon, often due to chronic constipation.
Diagnostics and Treatment
To diagnose Manx syndrome, your veterinarian will conduct a thorough medical history review and a complete physical examination. Diagnostic tests may include radiographs (X-rays), urinalysis, neurologic examinations, and bacterial cultures to detect urinary tract infections.
Unfortunately, there is no curative treatment for Manx syndrome. Treatment primarily focuses on supportive care and managing related issues. This may involve:
- Managing Incontinence: Providing hygiene, grooming, and manually emptying the bladder.
- Preventing Urine Scald: Keeping the cat clean and using diapers if tolerated.
- Treating Megacolon: Stool softeners to alleviate constipation.
- Preventing Future Breeding: Cats with Manx syndrome should not be bred to prevent suffering in offspring.
Regular veterinary care is essential to monitor and manage the condition and related complications effectively.
Manx syndrome is a challenging condition, both for affected cats and their owners, but with proper care and management, affected cats can lead relatively comfortable lives.
