Available DNA Tests for Dogs and Cats


Canine Myotonia Congenita (Code: C124)

TEST DESCRIPTION

Canine Myotonia Congenita is an inherited condition characterized by delayed relaxation of skeletal muscle after voluntary contraction without associated symptoms of weakness or muscular dystrophy. Recent molecular genetic studies have identified the CLCN1 gene encoding the skeletal muscle voltage-dependent chloride channel, ClC-1, as responsible for this condition in human, mouse, goat and dog forms of the disease. Myotonia congenita has been observed in certain dog breeds, and recently was described in Miniature Schnauzers. Myotonia in this dog breed exhibits many of the same features as human myotonia congenita including moderate to severe action myotonia, muscle hypertrophy, decreased myotonia severity with continued activity (`warm-up`), abnormal upper respiratory sounds especially when beginning to move, and low sarcolemmal chloride conductance.

DNA Test

This DNA test provides reliable identification of dogs that carry mutant gene(s). The DNA test allows a breeder to control the mutant gene frequency in Miniature Schnauzers thus preventing the production of puppies affected with Canine Myotonia Congenita. This DNA test accurately and specifically identifies normal, carriers (heterozygous) and affected dogs.
