Because of this mutation only two hair types seem to be present: guard hairs of irregular diameter and curved and thinner hairs. Thus, Sphynx is not completely hairless, having a fine down on the body and some light and wavy hair often present on the nose, tail, and toes. All the hairs lack a well-formed bulb, which probably explains why hairs are so easily dislodged, causing a lack of hair on the body but not a complete lack of hair production.
Test specific information
Symptoms will develop at a young age. Within a few hours to a maximum of several weeks after birth, the characteristics that go with these genetic effects will become visible.
Normally the result can be expected within 15 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.
This DNA test is available for the following breeds: Sphynx.
For this DNA test we accept the following materials: Blood EDTA, Blood Heparin, Swab, Tissue. Please contact PharmaDNA if you wish to submit other material as listed.
An animal can be free and has in that situation two healthy alleles. When used in breeding this animal will not become ill due to the disease. It cannot spread the disease in the population.An animal can be carrier and has in that situation one healthy and one disease allele. When used in breeding 50 percent of the offspring will receive the disease allele. Carriers will not become ill.An animal can be affected and has in that situation two disease alleles. When used in breeding all offspring will also receive the disease allele. Affected will become ill.
This genetic factor is inherited in an autosomal, recessive, mode. This means, that the individual can be free of the disease (homozygote normal), affected (homozygous affected) or carrier (heterozygous). Carriers may spread the mutation in a population without showing symptoms themselves. Because of this, it is extremely important to identify carriers correctly to prevent spreading of a mutation.
Severity of Disease
Factors influencing coat colour and coat types are usually not related to diseases.
