K657 Haemophilia B - 2

Background

Haemophilia B is a coagulation disorder caused by defects in the large and complex coagulation factor IX gene. The bleeding predisposition associated with haemophilia A results from a deficiency or dysfunction of IX, with the severity depending on the amount of residual enzyme activity.

Test specific information

-

Age

This disease leads to a reduction in the number of liveborn offspring. Depending on the disease, affected individuals may be stillborn or aborted.

Turn Around Time

The turn-around-time of a test depends to a large extent on the logistics of sample transportation to the laboratory. After receiving the sample at the test location, you can normally expect the result within 10 working days. A longer delivery time applies to tests carried out by a Partner Lab.

Location of disease or trait

This disease affects the composition of the blood, consequently influencing the coagulation of blood.

Breed dependence

This DNA test is available for the following breeds: Housecat Longhair, Housecat Shorthair. Additional information is available in the Frequently Asked Questions (FAQ).

Sample type

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

Result

The following results are possible for a female: the mode of inheritance is based on recessive or dominant patterns.

The following results are possible for a male:
- A male animal has the sex chromosome Y and a healthy allel. When used in breeding, this animal will not become affected by the disease, nor will the disease be inherited to the next generation.
- A male animal has the sex chromosome Y and a disease allel. When used in breeding, this animal will become affected by the disease. Also, male offspring will receive the Y-chromosome, whereas female offspring will receive the disease allele.

Inheritance

The disease is inherited in an X-chromosomal manner. This means, that female individuals can be free (homozygous normal), affected (homozygous affected) or carrier (heterozygous).

Male individuals carry only one copy of the X-chromosome, which results in the effect that male carriers will also be affected.

Female carriers may spread the disease in a population without showing symptoms themselves. Because of this, it is extremely important to identify carriers correctly to prevent spreading of a disease.
