Familial Shar-Pei Fever, also called Shar-Pei Autoinflammatory Disease (SPAID) is an inherited autoimmune condition characterised by recurrent fever attacks and arthritis (swollen and painful heels). Therefore it is also called “Swollen Hock Syndrome”. Clinical signs of SPAID are fever, pain in the hind legs, excessive drinking and excessive urination. A causal mutation responsible for the disease was identified in the MTBP gene.
Shar-Pei Fever can be treated by a veterinarian through painkillers and medication to support kidney functions and reduce fever.
Test specific information
It is likely that this mutation is an incomplete dominant inheritance in the Shar-Pei Dog. So, Shar-Pei dogs with one copy of the mutation are at higher risk for SPAID and dogs with two copies will be affected by SPAID.
‘Early onset’ – This phrase indicates, that the symptoms of the disease can be detected at a lower age. ‘Early onset’ is the opposite of ‘late onset’, in which symptoms may be present at later ages. The phrases are used because the mutation causing ´early onset´ symptoms may be different compared to the mutations causing ´late onset´ symptoms.
The Turnaround Time (TAT) depends on various factors, such as the shipment time of your sample to the test location, the test method(s) and whether the tests are performed completely or partially by a Partner Lab or Patent owner.
The TAT of tests performed at our facilities is normally 10 working days after receipt of the sample at the testing laboratory (VHL, VHP or Certagen). For tests performed by a Partner Laboratory (so-called "partner lab test") or patent owner, the TAT is at least 20 working days after receipt of your sample. Because the shipment time to our Partner Labs or patent owner may vary due to factors we cannot influence, the mentioned 20 working days are therefore an estimate.
Sometimes it is necessary to re-run your sample. We call this a retest. In that case, the TAT will of course be extended.
Location of disease or trait
Trait or disease of diverse organs and tissues in the whole body.
This DNA test is available for the following breeds: Shar Pei. Additional information is available in the Frequently Asked Questions (FAQ).
For this DNA test we accept the following materials: Blood EDTA, Blood Heparin, Semen, Swab, Tissue. Please contact Dr. Van Haeringen Laboratorium 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.
