Equine hyperkalemic periodic paralysis

Test code: GE001 - Detection of the gene responsible for hyperkalemic periodic paralysis in horses, by polymerase chain reaction (PCR).

Hyperkalemic periodic paralysis (HYPP) is an autosomal dominant inherited disease affecting the muscle tissue of horses. It is usually caused by a point mutation in a protein that is part of the sodium channel in muscle cells. Sodium channels are "pores" in the muscle cell that regulate contraction of the muscle fibers.

Muscles of affected horses can be overly excitable and contract involuntarily. This occurs when potassium levels change in the blood, for example when fasting is followed by consumption of a high potassium feed such as alfalfa. High levels of potassium in blood (hyperkalemia) cause the muscles to contract more readily than normal, and thus affected horses will develop sporadic episodes of muscle tremors or paralysis.

Most sporadic mutations in this gene are incompatible with survival. However, one mutation, P1416L, that can be traced back through descendants of the American Quarter Horse sire Impressive (Tryon et al., 2009), produces a functional, yet altered, sodium ion channel. Because of the lesser severity of the deformation, horses with the P1416L mutation can survive but still suffer from HYPP. This gene mutation is not a product of inbreeding; the mutation inadvertently became widespread when breeders sought to produce horses with heavy musculature.
