Myotonia Congenita

Breed: Miniature Schnauzer/ Black

Generic Phene Data

General

Disease Name
Myotonia Congenita
Mutation
c.2665insA
Mutation 2
c.803C>T
Test Type
Genetic Disease/Disorder
Details
Myotonia is a genetic muscle disorder characterized by slow relaxation of skeletal muscles. Signs include: stiff gait, skeletal muscle hypertrophy, difficulty swallowing, difficulty standing up/rising, increased respiratory sounds, generalised stiffness, and increased salivation. Age of onset 2-3 months of age. Signs can vary somewhat by breed/type.
Details 2
Heritable myotonia is a genetic muscle disorder characterized by slow relaxation of skeletal muscles. The main clinical signs are skeletal muscle stiffness, especially after vigorous contraction, and muscle hypertrophy. Muscle stiffness may be enhanced by inactivity, and often is relieved by exercise. (From Finnigan et al, 2007)

Application in the Breed
Carriers may be bred to normal animals (N/mc x N/N). Offspring should be tested before breeding. No breeding of two carriers (N/mc x N/mc) nor of affected animals (mc/mc). Stiffness when moving, severe overgrowth of the muscles. Predominant signs: stiff gait, skeletal muscle hypertrophy, difficulty swallowing, and increased salivation ( 2-3 months of age)
