Screening Scheme Description

DNA test - L-2HGA
L-2-hydroxyglutaric aciduria

Details about the disease

L-2-HGA is a neurometabolic disorder (a metabolic disorder that effects the nervous system), characterised by elevated levels of L-2-hydroxyglutaric acid in urine, plasma and cerebrospinal fluid.

Clinical signs

L-2-HGA affects the central nervous system, with clinical signs usually apparent between 6 months and one year (although they can appear later). Clinical effects include epileptic seizures, "wobbly" gait, tremors, and muscle stiffness as a result of exercise or excitement and altered behaviour.

How it is inherited

The disease is described as an autosomal recessive condition. This means that a dog must inherit two copies of an abnormal gene (one from its mother and one from its father) before its health is affected. A dog that inherits only one copy of the abnormal gene (from its mother or its father) will have no signs of the disease, but will be a carrier and may pass the gene on to any offspring.

Which laboratories test for this condition?

How to responsibly breed from your DNA tested dog

If, once your dog is DNA tested, you would like to find out what their DNA test results mean, or how to select the right mate to avoid producing affected puppies, then please read our breeding advice and information on the following link http://bit.ly/2oSbtnn.

How to find out if a potential mate has been DNA tested

The Kennel Club’s “Health Test Results Finder” allows you to find the results of DNA tests carried out as part of official Kennel Club DNA testing schemes for any dog on the Kennel Club’s breed register. To access this free health tool, please follow this link http://bit.ly/1jyCFnc.
