Burmese Hypokalemia (Familial Episodic Hypokalaemic Polymyopathy) is a recessive genetic characterized by episodes of low serum potassium levels and high CPK (creatine phosphate kinase, an enzyme that indicates muscle damage). Clinical Symptoms include episodes of skeletal muscle weakness which can affect all muscles of the cat body or it can be restricted to certain muscles. This is mostly seen in the neck muscles, but sometimes it affects the limbs only. As a result affected cats may have problems with walking and holding their head correctly. The disease is not typically fatal and can usually be managed by adding potassium supplements to the diet (consult yuor vet if your cat is affected). The disease affects Burmese and Burmese related breeds such as Burmilla, Bombay, Cornish Rex, Devon Rex, Singapura, Sphynx, Australian Mist, Tiffanie, and Tonkinese. The genetic mutation responsible for this disease has been identified by a team of researchers from the University of Bristol (England), the Lyons Feline Genetics Research Laboratory at UC Davis, University of Sydney, Massey University and Justus Liebig University. This discovery has allowed development of a genetic test that allows identification of carrier and affected cats.
