PCK2-related paroxysmal dyskinesia · Paroxysmale Dyskinesie (PCK2) · PCK2-PxD · PCK2-dyskinesia
This is an inherited neurological disorder in Shetland Sheepdogs caused by a mutation in the PCK2 gene, which affects cellular energy metabolism. This genetic defect leads to sudden, temporary episodes of involuntary muscle movements and spasms while the dog remains fully conscious. Because it is an autosomal-dominant condition, a dog only needs to inherit one copy of the mutated gene from a parent to be at risk.
Owners will typically notice sudden episodes of muscle stiffness, cramping, or coordination issues starting between a few months and several years of age. These episodes can last from minutes to hours, but the dog behaves completely normally between them.
There is no cure, but the condition can be managed long-term through stress reduction, dietary changes, or medication. Lifelong management and diagnostic costs generally range from 600 to 3,500 EUR.
