This autosomal recessive inherited pathogenic condition affects skeletal muscle ion channels. Clinical signs are hypertrophic skeletal muscles and difficulty in rising after a period of rest. Also characteristic for this disorder is a stiff, lanky gait which can be improved by training and difficulties in swallowing as well as excess salivation. All affected miniature Schnauzers exhibit an abnormal set of teeth and overbite, sometimes also abnormal barking.
