Uridine Monophosphate Synthase (UMPS) is an enzyme, which is responsible for the transition of a specific acid to Uridine Monophosphate (UMP), which is an essential element of pyrimidines (building blocks of DNA). The enzyme has two important functions in the final stages of the process to make pyrimidines, which causes a defect in UMPS to have major consequences.The disease is mainly present in Holstein cattle. The rare hereditary disease causes early abortion of calves, which is caused due to the fact that the defect enzyme looses its function. Embryos affected by DUMPS die in the uterus after about 40 days of pregnancy. Cattle which are carrier of the disease show no symptoms, but express only half of the normal amount of UMPS.

Test specific information



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 is lethal, and results in stilborn animals or embryonic death.

Breed dependence

For this test samples from all breeds are accepted.

Sample type

For this DNA test we accept the following materials: Hair, Semen, Blood EDTA, Blood Heparin, 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.
