Background

During the last decades, a large number of scientific publications have described the genetic principles of coat colour and coat variation. Coat colours and coat variations are influenced by many hereditary factors. The DNA-tests are based on physiological effects in the body, in which the production and distribution of pigments result in many coat colour variants. In several cases, the coat colour of an animal may only be decided using DNA-tests.The Agouti gene (ASIP gene) is responsible for the production of a protein that regulates the distribution of black pigment (eumelanin) within the hair shaft. This gene is also known as the A-locus and is responsible for ticking and causes the individual hairs to have bands of light and heavy pigmentation. The agouti band can be seen in both black-based and red-based colours. The Coat Colour Agouti test (K757) tests for the genetic status of the A-locus. The A-locus has two variants (alleles). The allele A is dominant and produces ticked coat, hair shafts with alternating bands of yellow and black colour, ending with black tips (similar to the coat of a wild mouse or rabbit).The recessive allele produces a cat that is ?self?coloured (solid). Only when the cat has two copies of the recessive allele a the coat colour is solid.Another system of pigmentation in cats produces the tabby patterns of dark stripes interspersed with the lighter agouti tipped hairs. Hairs in the darker stripes do not have the shift between black and yellow pigment production and remain uniformly dark. The effect of the agouti protein on orange pigment is limited, thus tabby striping may still be seen on cats that are a/a for agouti.

Test specific information

This test is also included in a Combination Package Coat Colour. Since 2015, two brands have been developed. CombiGen? is mainly directed at veterinarian applications, whereas CombiBreed? is mainly directed at breeders and/or owners.Detailed information about Coat Colours and Coat Variation is presented at www.pharmaDNA.com.

Age

Most coat colours and coat types are usually visible directly after birth.

Throughput

Normally the result can be expected within 25 working days. This turn-around-time starts when both the sample and the fully filled-out and signed submission form have been received.

Location of disease or trait

Genetic factors influencing coat colours and coat types are usually visible on the outside of an individual. Several factors may be hidden by the external variation.

Breed dependence

For this test samples from all breeds are accepted.

Sample type

For this DNA test we accept the following materials: Blood EDTA, Swab, Blood Heparin, Tissue. Please contact PharmaDNA if you wish to submit other material as listed.

Result

Coat colours are based on many genetic factors. For each factor, a separate test result will be returned.

Inheritance

Various genetic factors influencing coat colour and coat types are inherited in a dominant or recessive mode. Coat colours are influenced by a large number of genetic factors.

Severity of Disease

Genetic characteristics are not a disease.
