Which Musculoskeletal Disease Is Genetically Passed Down To Descendants Of Impressive A Famous Quarter Horse Stallion?

Hyperkalemic periodic paralysis (HYPP), also known as Impressive Syndrome, is an inherited autosomal dominant disorder which affects sodium channels in muscle cells and the ability to regulate potassium levels in the blood.

Hyperkalemic periodic paralysis.

What disease did Impressive horses have?

HYPP
HYPP is a genetic disease noted by mild to severe episodes of muscle spasms and trembling. HYPP links back to the Quarter Horse sire Impressive. Breeders should refrain from using any HYPP horses for breeding. Lowering diet potassium levels and providing regular exercise can help manage HYPP in affected horses.

Which Quarter Horse stallion was responsible for the HYPP being spread throughout the breed?

The disease is linked to the bloodline of the famous American Quarter Horse stallion Impressive, who has over 55,000 living descendants as of 2003.

What is the Impressive gene in horses?

HYPP is a dominant gene, and as such, all animals with even one copy of the gene, identified as “N/H”, will exhibit some symptoms of the disease. Horses with two copies, identified as “H/H.” will always pass on the condition, and research suggests that H/H horses may have more severe symptoms than N/H horses.

What horses have HYPP?

Hyperkalemic periodic paralysis (HYPP) is an inherited disease of the muscles primarily found in Quarter Horses which is characterized by sporadic episodes of muscle tremors or paralysis.

Do all Impressive horses have HYPP?

Not all horses of that line had HYPP, but all horses with HYPP were descended from Impressive himself. In 1994, a genetic test that utilized DNA from hair or blood, was perfected, this determined whether a horse had HYPP or not.

Is HYPP only in quarter horses?

This genetic defect has been identified in offspring of the American Quarter Horse sire, Impressive. To date, confirmed cases of HYPP have been restricted to descendants of this horse.

What causes HYPP?

HYPP is a muscular disease caused by a known genetic mutation with an autosomal dominant mode of inheritance. Affected horses can exhibit signs that include muscle tremors, weakness, paralysis and collapse. The signs of HYPP can be confused with other diseases and conditions.

What is the difference between PSSM and HYPP in horses?

Type 1 PSSM is a common cause for tie-up signs in Quarter Horses, Paints, Appaloosas, and warmbloods. PSSM can often be managed with diet and exercise changes but there is no cure or medication used to treat it. HYPP is an inherited muscle disease causing an abnormality in how muscle cells manage electrolytes.

What bloodlines carry GBED?

GBED is found in Quarter Horse or related bloodlines that causes late-term abortion or death of foals by a few months of age.

What are some inherited traits of a horse?

Many characteristics such as coat color, height, athletic ability, and behavioral tendencies are genetic in nature.

Which of the following diseases primarily affects Quarter Horses Draft horses and Warmbloods?

Polysaccharide storage myopathy is a muscle disease that occurs primarily in horses with Quarter Horse bloodlines such as Quarter Horses, Paint Horses and Appaloosas. Polysaccharide storage myopathy also occurs in other breeds including Drafts, Draft crossbreeds, and Warmbloods.

What special conditions do horses require in order to thrive?

Horses need a regular supply of food and water
of food a day and drink at least eight gallons of water. Because their stomachs are relatively small and their digestive systems surprisingly delicate, horses need to nibble or graze throughout the day, rather than have one or two meals a day.

Is HYPP the same as PSSM?

Hyperkalemic periodic paralysis HYPP is a completely separate muscle disorder in Quarter Horses from PSSM1. The two diseases have different clinical signs, different causes and different treatments.

What is the lethal white gene in horses?

OLWS is a genetic mutation that affects horses with white markings and can lead to death in foals. Foals with two copies of this gene are born white with blue eyes and have intestines that don’t fully develop. There is no treatment for OLWS. Don’t breed carriers of the gene with each other.

What is a Level 2 horse?

RIDING ABILITY – LEVEL 2
The intermediate rider is able to mount and dismount their horse unassisted, use basic riding aids, ride at a rising trot for at least 10 minutes, to change and control the pace from a walk to a trot and comfortably canter over short distances.

What is PSSM positive in horses?

Polysaccharide storage myopathy (PSSM) is a disease that results in an abnormal accumulation of glycogen (sugar) in the muscles. Clinical signs may include reluctance to move, sweating, and muscle tremors, also known as “tying-up”.

Why does horses with HYPP need potassium?

As potassium levels rise further in the bloodstream, the muscles become unable to contract, and the horse becomes paralyzed. This cycle continues until excessive potassium is excreted through the urine or resorption of potassium into cells occurs. The physical effects of HYPP vary considerably.

How is HYPP diagnosed?

HYPP is characterized by sporadic attacks of muscle tremors, weakness and/or collapse, lasting for variable periods of time. Diagnosis is based on physical findings in association with hyperkalemia.

What diseases are Quarter Horses prone to?

• Glycogen Branching Enzyme Deficiency (GBED)
• Hereditary Equine Regional Dermal Asthenia (HERDA)
• Hyperkalemic Periodic Paralysis (HYPP)
• Myosin-Heavy Chain Myopathy (MYHM)
• Malignant Hyperthermia (MH)
• Polysaccharide Storage Myopathy (PSSM1)

Are Quarter Horses cold bloods?

Q: Is a Quarter Horse cold blood? No, a Quarter Horse is not considered to be in the ‘cold blooded’ category of horses. Examples of cold-blooded horse breeds are draft horses such as Percherons, Clydesdales, and Belgians. These horses were bred to do heavy work with a calm temperament.
