H367 IGS (Selective Cobalamin Malabsorption) 2

Background

Vitamin B12 malabsorbtion is a serious and potentially life-threatening metabolic disease in puppies and young dogs. In affected dogs, the lining of the lower intestine will not absorb vitamin B12. The disease can cause a wide range of clinical problems, including lack of appetite, lethargy, failure to thrive, wasting, vomiting, seizures, or general ill-health. The most serious complications include abnormalities of the blood and nervous system that are lethal if untreated. Fortunately, with proper diagnosis and relatively inexpensive treatment, affected dogs can be kept in remission throughout their lives.

Test specific information

-

Age

‘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.

Throughput

Normally the result can be expected within 10 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

This disease is present in the entire body, but causes main effects in the internal organs such as stomach, intestinal tract, liver and / or kidneys. In a number of cases, the disease affects one major internal organ.

Breed dependence

This DNA test is available for the following breeds: Border Collie, Bearded Collie, Rough Collies, Smooth Collies. Additional information is available in the Frequently Asked Questions (FAQ).

Sample type

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.

Result

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.

Inheritance

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.
