Frisian dwarfism (FD) causes abnormal growth of the legs and chest, resulting in severe health problems. The disease is inherited autosomal recessively.

Furnishing (wire-haired) refers to the length and texture of the hair. The dog has rather wavy to curly coat and very pronounced hair on eyebrows and beard. This coat structure occurs in many different breeds.

The SynchroGait®-Test is able to identify the genetic key factor responsible for the leg coordination. With this information we can predict a horse’s performance in two different categories:

• Flying pace for breeds participating in harness-races
• Natural capacity for alternative gaits in certain breeds ("gaited" horses)

A gene defect is the deviation of a certain genetic information that leads to a defective gene product.
The defective gene product subsequently leads to symptoms of malfunction, which can vary in severity depending on the type of defect and the importance of the affected gene.

Glanzmann Thrombasthenia (Equine coagulopathy - GT) is a blood clotting disorder in horses and causes recurrent nosebleeds and frequent other bleeding. This is caused by a dysfunction of the blood platelets (thrombocytes).

Glycogen Storage Disease IV (GSD IV) causes energy deficiency in muscles and organs due to a disorder in glycogen metabolism. The disease occurs in the Quarter Horse and related breeds.

Synonym: Glycogen Branching Enzyme Deficiency (GBED)

Glycogen storage disease IIIa (GSD 3a) is a metabolic disease. In type 3a, glycogen cannot be metabolised due to an enzyme defect. This leads to glycogen accumulation in the liver and muscles, which are impaired in their function. The symptoms of lethargy, exercise intolerance and collapse occur at the age of 14 months.

The disease occurs in the Curly Coated Retriever. The inheritance is autosomal recessive.

Golden Retriever Muscle Dystrophy (GRMD) is a degenerative muscle disease in which muscle fibre degeneration and necrosis occur due to a malformation of the dystrophin protein. Affected dogs suffer from muscle wasting, weakness and feeding difficulties. The poor quality of life often leads to euthanasia.

The disease occurs in Golden Retrievers and is inherited in an X-linked recessive manner.

Synonym: X-linked muscular dystrophy, Duchenne muscular dystrophy, Dystrophin-deficient muscular dystrophy

Due to the Grey mutation, normally coloured foals first turn grey and later white. They slowly "lose" their colour, as pigment-producing cells gradually stop to produce pigment and the hairs that grow back have less and less colour pigments and eventually none at all. Transitions patterns such as "dapple grey" and "flea-bitten" etc. develop.

The responsible gene (STX17) is involved in cancer pathways. The duplication that causes the grey colour also predisposes grey horses to developing melanoma.

The dog has a light face mask with so-called "widow's peak". This colour pattern is caused by the Eg allele of the extension locus.
