Congenital Myasthenic Syndrome (Old Danish Pointer Type)

Category:

Nervous system / Neurologic - Associated with the brain, spinal cord and nerves

Gene:

Choline O-acetyltransferase (CHAT) on chromosome 28

Variant Detected:

c.85G>A

Severity:

Low-Moderate. This disease can cause some discomfort and/or dysfunction in the affected animal. It does not generally affect life expectancy.

Mode of Inheritance:

Autosomal Recessive

Recommended Screening:

Genetic testing of the CHAT gene will reliably determine if a dog is a genetic carrier of congenital myasthenic syndrome (Old Danish Pointer Type).
